One way to measure g on another planet or moon by remote sensing is to measure how long it takes an object to fall a given distance. a lander vehicle on a distant planet records the fact that it takes 3.17 s for a ball to fall freely 11.26 m, starting from rest.
a. what is the acceleration due to gravity on that planet?
b. how fast is the ball moving just as it lands in m/s?

A12-g wad of sticky clay is hurled horizontally at a 100-g wooden block initially at rest on a horizontal surface. the clay sticks to the block. after impact, the block slides 7.5 m before coming to rest. if the coefficient of friction between the block and the surface is 0.65, what was the speed of the clay immediately before the impact?
