(d) It is 6 times larger. (e) It is 36 times larger.
An attacker at the base of a castle wall 3.65 m high throws a rock straight up with speed 7.4m/s from a height of 1.55m above the ground. a) will the rock reach the top? b) if so what is its speed at the top? if not, what initial speed must it have to reach the top? c) find the change in speed of a rock thrown straight down from the top of the wall at an initial speed of 7.4 m/s and moving between the same two points. d) does the change in speed of the downward moving rock agree with the magnitude of the speed change of the rock moving upward between the same elevations? e) why does this agree or not agree.

An attacker at the base of a castle wall 3.67 m high throws a rock straight up with speed 8.10 m/s at a height of 1.53 m above the ground. Will the rock reach the top of the wall? what is the rock's speed at the top? If not, what initial speed must the rock have to reach the top? Find the change in the speed of a rock thrown straight down from the top of the wall at an initial speed of 8.10 m/s and moving between the same two points.
A ball is thrown upward from the top of a tall building so that it lands on the ground at the base of the building. The ball reaches a maximum height of 105 m above the ground. The ball is in the air for a total of 5.32 s. Air resistance can be neglected. Use up as the +y-direction and down as the -y-direction. What is the initial velocity of the ball? What is the height of the building? What is the velocity of the ball, just before it hits the ground?
A ball is projected vertically up from the floor of a room. The ball experiences air resistance that is proportional to speed of the ball. Just before hitting the ceiling the speed of the ball is 10 m/s and its retardation is 2g. The ball rebounds from the ceiling without any loss of speed and falls on the floor 2s after making impact with the ceiling. How high is the ceiling? Take g = 10 m/s².
A rock is thrown off a vertical cliff at an angle of 65 degrees above horizontal. The cliff is 67.2 m high and the ground extends horizontally from the base. The initial speed of the rock is 24.4 m/s. Neglect air resistance. a) How high above the ground, in meters, is the rock 2.03 s before it hits the ground? b) How far horizontally from the cliff, in meters, is the rock 2.03 s before it hits the ground?

Jenny and Jack throw identical balls off a tall building at the same time. The ground near the building is flat. Jenny throws her ball straight downward. Jack throws his ball downward and outward such that the angle between the initial velocity of the ball and the horizon is 30°. Jack throws the ball with a speed twice that of Jenny's ball. If air resistance is negligible, which ball hits the ground first? Jenny's ball hits first. It is impossible to know from the information given. Jack's ball hits first. They hit at the same time
