A solid sphere and a solid cylinder each of mass M and radius R are rolling with a linear speed on a flat surface without slipping.Let L(1) be magnitude of the angular momentum of the sphere with respect to a fixed point along the path of the sphere. Likewise L(2) be the magnitude of angular momentum of the cylinder with respect to the same fixed point along its path.The ratio (L(1))/(L(2)) is

A bus moves from rest with a uniform acceleration of 2 m/s2 for the first 10 s. It then accelerate at a uniform rate of 1 m/s2 for another 15 s. It continues at constant speed for 70 s and finally comes to rest in 20 s by uniform deceleration. Draw its velocity time graph and calculate total distance covered.
