A 4.0 kg mass is 1.0 m away from a 7.0 kg mass. What is the gravitational force between the two masses? (Remember to
use the gravitational constant, G = 6.67 x 10-11 Nx m2/ kg?, in your calculation.)
6.67 x 101°N
1.9 x 10-N
3.8 N
6.67 x 10-N

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.
