a. A child is sitting on the outer edge of a merry-go-round thatis 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 gramsat a muzzle velocity of 696 m/s. What should the recoil speed ofthe 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/simmediately after being struck. If the club and ball were incontact for 0.59 ms, what is the average force exerted on theball?
d. An undiscovered planet many light years from Earth has onemoon in orbit. This moon takes 16.8 days on average to complete anearly circular revolution around the planet. If the distance fromthe center of the moon to the surface of the planet is 432 x106 m and the planet has a radius of 4.14 x106 m, calculate the moon’s radial acceleration.
