A 9 kg asteroid is traveling through space at 2.5 m/s toward a spaceship. To avoid a collision, an astronaut, with the help of a backpack rocket, exerts a force of 25N on the asteroid in the opposite direction for 4 seconds. a) Find the asteroid s final speed. m/s (Hint: Assume the initial speed f the asteroid is in the positive x direction.) b) How long should she have pushed in order to just stop the asteroid? Time to stop asteroid = seconds

A 25g ball slides dowm a smooth inclined plane 0.850 m high that makes an angle of 35 degrees with the horizontal. The ball slides down into an open box of 150 g mass. The ball and the box slide off the end of a table 1.0 m high. a.) How far from the base of the table will the box and ball hit the ground? b.) What is their final velocity?
Sam, whose mass is 74.0 kg, takes off across level snow on his jet-powered skis. The skis have a thrust of 220.0 N and a coefficient of kinetic friction wtih the snow of 0.07. Unfortunately, the skis run out of fuel after only 11.5 seconds. What Sam's top speed (in m/s) assuming that the acceleration due to gravity is 9.80 m/s2? How far (in m) has Sam traveled when he finally coasts to a stop?
