Ignoring drag:
h=32.7*t-0.5*g*t2
Where g is about equal to 32.2 ft/sec2

What does vt mean in the vertical motion formula?
it means initial upwards height times time in seconds
Question-1 A body is thrown vertically upwards The distance st above the ground after t seconds is given by st 20t-5t2 meters?
The equation for vertical motion is y = v0t + .5at2. y is vertical displacement v0 is initial vertical velocity a is acceleration (in meters, normal gravitational acceleration is about -9.8 m/s/s, assuming positive y is upward displacement and negative y is downward displacement)
When A baseball is hit straight up at an initial velocity of 100 ms how long will it take to hit the ground?
The baseball will travel upwards until its velocity is zero and then fall back down again. The acceleration of the baseball is the constant acceleration due to gravity acting in a downwards direction. The time taken to fall back down will be the same as the time to climb, thus the total time is twice the climb time. Use Netwon's equations of motion and ignore air resistance, the time to the top of the climb is: v = u + at → t = v - u/a v = final velocity = 0 m/s at the top of the climb u = initial velocity = +100 m/s a = acceleration = -g m/s² t_top = 0 - (100 m/s) / (-g m/s²) = 100/g s → t_total = 2 × t_top = 2 × 100/g s = 200/g s ≈ 200/9.81 s ≈ 20.4 s
Is the total time of a ball thrown upwards is it equal to the total time of the downward velocity?
There's no such thing as "time of the downward velocity", but I think I get the sense of your question. If the effects of air resistance can be disregarded, then any object thrown upwards spends half of its time rising, and the identical amount of time falling back to the height of your hand when you let it go.
What is maximum velocity?
maximum velocity is the highest possibly speed an object can travel before the forces acting on it reach an equilibrium and it is no longer able to accelerate. For example a parachutist will fall and accelerate rapidly until the air resistance pushing upwards against her downward force becomes balanced and her speed is steady, its more commonly known as 'terminal velocity' not maximum.
What does vt mean in the vertical motion formula?
it means initial upwards height times time in seconds
When object moves upwards what is the velocity and acceleration?
When an object is moving upwards, its velocity is directed upwards. If the object is near the Earth or any other planet, then its acceleration is directed downwards, which also means that its upward velocity is decreasing.
What is its velocity at the highest point of a ball vertically upwards?
In that case, the velocity is zero.
An object is thrown vertically upwards from the top of a tower of height 39.2 meters reach the ground in 4 secons Find the velocity with which it is thrown upwards?
Using the equation: x=vot+(1/2)at2 x: -39.2m (though the object is thrown upwards, its total displacement is just the amount it fell from the tower). vo: initial velocity t: 4 s a: -9.8m/s2 (assuming we're on the earth's surface) -39.2=vo(4 s)+(1/2) (-9.8m/s2)(4 s)2 ((78.4 m - 39.2 m)/ 4 s) = v0 So the initial velocity is 9.8 m/s.
What makes a thrown upwards body to stop for some few seconds before desendeing down?
It DOES NOT stop for a 'few seconds' . It stop only for an instant as its movement changes from upwards to downwards.
What is the velocity of object when it is thrown above?
The velocity of such an object changes all the time. Assuming you throw something directly upwards and there is no wind, it will go upwards, slower and slower, until it reaches its highest point. At that moment, its velocity is zero. Then, still as a result of gravity, it will move downward, faster and faster.
When is velocity antiparallel to acceleration?
when a ball is thrown upwards velocity increases but acceleration decreases hence making it anti parallel to each other
How do you write the word bound in Chinese?
* the line or plane indicating the limit or extent of something * a light, self-propelled movement upwards or forwards
How fast must an object be thrown up if it is to stay in the air for 5 seconds before hitting the ground again?
An object can be thrown vertically upwards or at an angle to the ground, in both cases it is needed that time of flight be 5 seconds. This means it's time of ascent (going up) is 2.5 seconds and time of descent(coming down) is also 2.5 seconds. So, it reaches highest point 2.5 seconds after it is thrown. At highest point the vertical component of velocity1 of the object becomes zero for an instance.Now, kinematics equation can be used to solve this.v = uy - g*twhere v is final velocity at top =0. uy is initial vertical velocity1. g is accleration due to gravity(9.8ms-2). t is time of ascent.putting values we get.0 = uy - 9.8 * 2.5or uy = 24.5 ms-1So we need to throw an object with vertical velocity = 24.5 meters per second so that it remains in air for 5 seconds.1. If object is thrown at an angle then vertical component of velocity of projection is taken.If object is thrown vertically upwards then vertical component of velocity of projection issame as velocity.vertical component of velocity of projection(uy) = u*sin(θ), where u is velocity of projectionand θ is angle of projection with respect to horizontal.2. Accleration due to gravity is different for different places. 9.8ms-2 is an approximatevalue.3. Here, air resistance and wind speeds have been neglected as they make the calculation verytedious and they are always varying from time to time and place to place.
When tossing a coin upwards what happens to its velocity while ascending what happens to its acceleration?
Its velocity decreases because gravity is pulling on it as it goes up. Its acceleration increases.
Definition for positive acceleration?
Acceleration occurs when velocity changes over time. The formula for it is as follows: a = (Vf - Vi) / t a: acceleration (meters/seconds2) Vf: Final velocity (meters/seconds) Vi: Initial Velocity (meters/seconds) t: Time (seconds)
How high does a rocket go?
It launches a a rocket vertically upwards with an initial speed of 40.0 m/s.
