The mass of the earth is 5.98 × 1024 kg. a 6.83 kg bowling ball initially at rest is dropped from a height of 2.12 m. the acceleration of gravity is 9.8 m/s^2. what is the speed of the earth coming up to meet the ball just before the ball hits the ground?
how do you solve this?

The 20@kg wheel has a radius of gyration about its center g of kg = 300 mm. when it is subjected to a couple moment of m = 50 n # m, it rolls without slipping. determine the angular velocity of the wheel after its mass center g has traveled through a distance of sg = 20 m, starting from rest.
