Step 1
Write down the information you already know:
v1= 50 feet per second [up]
a= 9.81 m/s2 [down]= -9.81 m/s2 [up] = -32.185 feet/s2 [down] (1 metre= 3.28083989501312 feet)
t= 3s
d= ?
Step 2
Solve:
d= v1t+(1/2)at2
d= 50(3)+(1/2)(-32.185)(3)2
d= 150-144.8325
d= 5.1675 feet
*Remember you need to add the initial height
d=5+5.1675
d= 10.1675 feet= 10 feet
Get the value of initial velocity. Get the angle of projection. Break initial velocity into components along x and y axis. Apply the equation of motion .
No. What counts in this case is the vertical component of the velocity, and the initial vertical velocity is zero, one way or another.
4ft*Ns=H
The answer depends on what gas the balloon contains, its initial velocity and the forces - gravity, buoyancy, cross-wind - acting on it.
If the initial velocity is 50 meters per second and the launch angle is 15 degrees what is the maximum height? Explain.
height=acceletation(t^2) + velocity(t) + initial height take (T final - T initial) /2 and place it in for time and there you go
4h
If you know the initial height and the length of the pendulum, then you have no use for the mass or the velocity. You already have the radius of a circle, and an arc for which you know the height of both ends. You can easily calculate the arc-length from these. And by the way . . . it'll be the same regardless of the mass or the max velocity. They don't matter.
initial velocity of the kick = 28.06 m/s
Get the value of initial velocity. Get the angle of projection. Break initial velocity into components along x and y axis. Apply the equation of motion .
9 km/s = 9000m/s Gravity decreases the velocity of the object by 9.8 m/s each second. The velocity at the top is 0 m/s Equation 1: Velocity final = velocity initial - (9.8 m/s × time) Final velocity =0 m/s Initial velocity = 9000m/s 0 = 9000 - 9.8 t 9.8 t = 9000 t = 9000÷ 9.8 t = 918 seconds Average velocity = (9000 + 0 ) ÷ 2 =4500 m/s Height = average velocity × time Height = 4500 m/s ×918 seconds=4,131,000 meters = 4,131 Km. If you do not want to round, this equation will find the answer more accurately. (velocity final) 2 - (velocity initial) 2 = 2 × acceleration × distance m/s2 0 - 90002 = 2 × 9.8 × d d = 4,132,653.061 meters = 4,132.653061Km I do not know of any measuring tool that measures that precisely!
if by 'you', you mean 'u' then u is the initial velocity v is the final velocity. you need to know the initial velocity in trajectory question (motion of an object through the air) to find height, acceleration, time etc.
4ft*Ns=H
No. What counts in this case is the vertical component of the velocity, and the initial vertical velocity is zero, one way or another.
Take acceleration of gravity = 9.8 m/s2 .The ball stops rising and starts falling in (100/9.8) seconds.It returns to the height of the bat in 2 x (100/9.8) = 20.408 seconds. (rounded)
To answer this question one would need to know the rock's initial height and velocity.
The answer depends on what gas the balloon contains, its initial velocity and the forces - gravity, buoyancy, cross-wind - acting on it.
