A rock thrown vertically upward from the surface of the moon at a velocity of24 m/sec reaches a height of s=24t-0.8t^2 meters in t seconds.a) Find the rock’s acceleration and velocity at time t.b) How long does it take the rock to reach its highest point?c) How high does the rock go?d) How long does it take the rock to reach half its maximum height?e) How long is the rock aloft?
An object located 3 earth radii ABOVE the earth's surface has a gravitational field of g/16 where g is the value at the earth's surface. true or false?

Problem 5: Near the surface of the Moon the acceleration due to gravity is roughly 1.67 m/s2 towards the lunar surface. The weapons platform begins to free-fall from 2 km up towards the surface initially with a velocity of O with all the members of the Presidential Time Squad onboard. A: What would be the velocity of the platform when it contacts the lunar surface? B: If James Monroe can re-activate the thrusters, they can provide an upwards acceleration of...
Can someone explain to me how to solve this one? 9. 1/1 points i Previous AnswersSerPSE10 13.А.P029 Let represent the difference in the gravitation al fields produced by the Moon at the points on the Earth's surface nearest to and farthest from the Moon. Find the fraction AgM 19, where g i s the Earth's gravitational field.

A horizontal launch took place on the moon where the gravitational acceleration is 1/6 that of earth. If the horizontal range were the same how must the initial velocity of the ball compare?
1) Strength of the electric force The earth and the moon exert attractive gravitational forces on one another according to Newton's law of gravitation. However, since the earth and the moon are electrically neutral (that is, the net charge of each planet is zero), they do not exert electrical forces on one another. Assume now that someone (aliens) removes some number N of electrons from both the earth and the moon, so that the two bodies now exhibit electrical repulsion...
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...
