A solid plastic sphere as shown in the figure (mass m=1 kg, and radius r = 10 cm ) initially at rest starts to rotate about its axis owing to a tangential force F as shown. The ball reaches the velocity v=10 m/s in 5 sec after the start. (a) Find the magnitude of the force F in Newtons. (b) If the force is applied as shown below, will the ball still need the same magnitude of F or not to reach that velocity in 5 sec, Yes or No? Explain.
