a. A child is sitting on the outer edge of a merry-go-round that is 3.19 m in diameter. If the merry-go-round makes 8.9 rev/min, what is the velocity of the child in m/s?

b. A markswoman of mass 73 kg shoots a bullet of mass 96 grams at a muzzle velocity of 696 m/s. What should the recoil speed of the markswoman be, if she is standing on a slick surface?

c. A golf ball of mass 0.050 kg has a velocity of 102 m/s immediately after being struck. If the club and ball were in contact for 0.59 ms, what is the average force exerted on the ball?

d. An undiscovered planet many light years from Earth has one moon in orbit. This moon takes 16.8 days on average to complete a nearly circular revolution around the planet. If the distance from the center of the moon to the surface of the planet is 432 x 106 m and the planet has a radius of 4.14 x 106 m, calculate the moon’s radial acceleration.
