A projectile is fired from the top of a cliff of height h above the ocean below. The projectile is fired at an angle θ above the horizontal and with an initial speed vi. (a) Find a symbolic expression in terms of the variables vi, g, and θ for the time at which the projectile reaches its maximum height. t = (b) Using the result of part (a), find an expression for the maximum height hmax above the ocean attained by the projectile in terms of h, vi, g, and θ. hmax =

A cannonball is fired horizontally from the top of a cliff. The cannon is at height H = 70.0m above ground level, and the ball is fired with initial horizontal speed v0. Assume acceleration due to gravity to be g = 9.80m/s2 . Part A Assume that the cannon is fired at time t=0 and that the cannonball hits the ground at time tg. What is the y position of the cannonball at the time tg/2? Answer is 52.5 Part...

In the figure, a stone is projected at a cliff of height
h with an initial speed of 47.0 m/s directed at an angle
θ0 = 54.0° above the horizontal. The stone
strikes at A, 5.48 s after launching. Find
(a) the height h of the cliff,
(b) the speed of the stone just before impact at
A, and (c)the maximum height H
reached above the ground. Use g=9.80

1: A projectile is launched from the top edge of a cliff of height h. The launcher is to deliver a package to some hikers stranded in the valley below. From GPS readings it is known that the hikers are a distance d (known) from the base of the cliff. If the projectile launcher is pointed at an angle θ (known), calculate the speed at which the projectile should be launched. 2: For this problem the heights are low enough...
