From a height of 1.5 m above the surface of the moon (no friction) a penny is dropped. The travel time and the velocity at arrival on the ground are ...?
Homework Answers
Acceleration due to gravity at moon, a = 1.622 m/s^2
h = 1.5 m
h = u*t + 1/2*a*t^2
1.5 = 0 + 1/2*1.622*t^2
t = 1.36 s
V = u + a*t
V = 0 + 1.622 * 1.36
V = 2.21 m/s

An attacker at the base of a castle wall 3.65 m high throws a rock straight up with speed 7.40 m/s from a height of 1.55 m above the ground.
a. An attacker at the base of a castle wall 3.65 m high throws a rock straight up with speed 7.40 m/s from a height of 1.55 m above the ground. Will the rock reach the top of the wall? If so, how fast is it moving when it reaches the top. If not, what initial speed must it have to reach the top? b. To defend the castle, a rock is thrown downwards from the top of the wall with...

There is a planet with two moons, Moon D and Moon P. Moon A is located in a stable circular orbit 2398 km from the surface of the planet, has an orbital period of 19 hours, and was a magnificent moon which served as the intellectual center of the whole sector. The other moon - Moon B - is a considerably smaller body. Moon D is in a stable circular orbit 59850 km from the surface of the planet and...

A ball is dropped from a height 24 m above the ground at t=0.0. Each time it bounces from the ground, its rebound speed is 60% of its impact speed. At the instant the first ball hits the ground, a second ball is released from the same place. Take g = 9.8 m/s2. At what height above the ground will they collide? (Take the ground as y=0.0 m)
