Question

A projectile is fired from ground level at time t=0, at an angle with respect to the horizontal. It has an initial speed v0. In this problem we are assuming that the ground is level.

Part A

Find the time tH it takes the projectile to reach its maximum height.

Express tH in terms of v0, ?, and g (the magnitude of the acceleration due to gravity).

Part B

Find tR, the time at which the projectile hits the ground.

Express the time in terms of v0, ?, and g.

Part C

Find H, the maximum height attained by the projectile.

Express the maximum height in terms of v0, ?, and g.

Part D

Find the total distance R (often called the range) traveled in the x direction; in other words, find where the projectile lands.

Express the range in terms of v0, ?, and g.

Explanation / Answer

A)
TH = [ Vo sin ?] / g

B)
TR = 2*[ Vo sin ?] / g

C)

H = [ Vo sin ?] /(2g)

D)
R = ( Vo /g)sin 2?
