#2 a car accelerates from rest at 4 m/s^2. what is the velocity of the car after 4 second? #3 what is the distance traveled by the car in problem # 2, in 3 seconds?

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.
