By the Way, guys, this is based on the equation H= -16t2+vt+s

How long does it take to hit the ground from 28000 feet high?
The answer will depend on what "it" is, and on what its initial velocity is.
Will a ball drop rest reach the ground quicker than the one lunched from the same height but with and initial horizontal velocity?
No. What counts in this case is the vertical component of the velocity, and the initial vertical velocity is zero, one way or another.
An arrow is shot straight up at an initial velocity of 250ms How long will it take to hit the ground?
This is a velocity question so u need to use uvaxt
If a ball is dropped from a building that is 200 feet above ground What will the velocity be when t is 1?
height(s)=1/2(u+v)t 200=1/2(0+v)*1v=400ft/secu = initial speedv=final speed
A brick is released with no initial speed from the roof of a building and strikes the ground in 2.00 s encountering no appreciable air drag How tall in meters is the building?
19.6m
How does initial velocity affect the projectile in range?
The initial velocity of a projectile affects its range by determining how far the projectile will travel horizontally before hitting the ground. A higher initial velocity will result in a longer range because the projectile has more speed to overcome air resistance and travel further. Conversely, a lower initial velocity will result in a shorter range as the projectile doesn't travel as far before hitting the ground.
How do initial velocity affect range and height of a projectile?
Increasing the initial velocity of a projectile will increase both its range and height. Higher initial velocity means the projectile will travel further before hitting the ground, resulting in greater range. Additionally, the increased speed helps the projectile reach a higher peak height before it begins to descend back down.
A brick is thrown vertically upward with an initial speed of 2.60 meter per sec from the roof of a building If the building is 100.0 m tall how much time passes before the brick lands on the ground?
Using the kinematic equation ( \text{final velocity}^2 = \text{initial velocity}^2 + 2 \times \text{acceleration} \times \text{distance} ) where final velocity is 0 (at the top) and initial velocity is 2.6 m/s, acceleration due to gravity is -9.8 m/sĀ², and distance is 100 m, you can solve for time to get approximately 5.02 seconds.
What is A football kicked off at an angle 20 from the ground reaches a maximum height of 4.7 m What is the initial velocity of the kick?
To find the initial velocity of the kick, you can use the equation for projectile motion. The maximum height reached by the football is related to the initial vertical velocity component. By using trigonometric functions, you can determine the initial vertical velocity component and then calculate the initial velocity of the kick.
Which information is needed to find the time a projectile is in motion?
The object's initial distance above the ground The object's initial velocity
What is the velocity of the tomato when it hits the ground?
The velocity of the tomato when it hits the ground will be determined by its initial velocity, the force of gravity acting upon it, and any air resistance. It will likely be accelerating towards the ground due to gravity until it reaches its terminal velocity upon impact.
How long does it take to hit the ground from 28000 feet high?
The answer will depend on what "it" is, and on what its initial velocity is.
Why does a ball you toss into the air not fall right away to the floor?
The ball is thrown with an initial velocity, and gravity slows it down as it rises. At its peak, the ball's velocity is zero before it begins to fall back to the ground. This is due to the balance between the initial force and gravity acting on the ball.
Will a ball drop rest reach the ground quicker than the one lunched from the same height but with and initial horizontal velocity?
No. What counts in this case is the vertical component of the velocity, and the initial vertical velocity is zero, one way or another.
What is the rock's approximate velocity just prior to hitting the ground?
To answer this question one would need to know the rock's initial height and velocity.
When a wet ball is thrown to ground it has more velocity after it hits ground than at throwing Explain Why?
This result is because the wet ball carries more inertia to weight ratio before hitting the ground , it then compresses, loses some of the liquid weight, becomes lighter, and because of the initial inertial force, can therefore leave the ground at a greater velocity
How long will it take to hit the ground if a baseballl is hit straight up at an initial velocity of 100 ms?
Assuming the acceleration due to gravity is -9.81 m/s^2, the time it takes for the baseball to hit the ground can be calculated using the formula: time = (final velocity - initial velocity) / acceleration. In this case, the final velocity will be 0 m/s when the baseball hits the ground. Calculating it would give you the time it takes for the baseball to hit the ground.
