When a pencil cell is released from a ce...

When a pencil cell is released from a certain point on an inclined wooden board, it travels a distance of 35 cm on floor board, it travels a distance of 20 cm on floor B before coming to rest. Which floor, A or B, offers greater friction ? Give reason for your answer.

Text Solution

Verified by Experts

Floor B offers greater friction (because it makes the moving pencil cell stop at a lesser distance of 20 cm)

A ball of mass m is attached to a cord of length L , pivoted at point O , as shown in Fig. The ball is released from rest at point A, swings down and makes an inelastic collision with a block of mass 2m kept on a rough horizontal floor. The coefficient of restitution of collision is e = 2//3 and coefficient of friction between block and surface is After collision, the ball comes momentarily to rest at C when cord makes an angle of theta with the vertical and block moves a distance of 3L//2 on rough horizontal floor before stopping. The values of mu and theta are, respectively,
