Compare the results of applying the acceleration equation in the following 2 cases : (1) an object that goes from 0 to 10 m/s in 4 s , and (2) then goes from 10 m/s to 30 m/s in 8s. a= (Vf-Vs)/t

The 10-kg double wheel with radius of gyration of 125mm about o is connected to the spring of stiffness k = 600 n/m by a cord which is wrapped securely around the inner hub. if the wheel is released from rest on the incline with the spring stretched 225 mm, calculate the maximum velocity v of its center o during the ensuing motion. the wheel rolls without slipping
