A block of mass 8 kg is placed on a trolley moving with acceleration 4 m/s2. Pseudo force acting on block as seen by a man on ground is
Block A and B have masses of 2kg and 3kg respectively. The ground is smooth. Pis an external force of 10N.The force exerted by B on A is
A body of mass 2 kg moving on a horizontal surface with an initial velocity of 4 m/sec comes to rest after 2 sec. If one wants to keep this body moving on the same surface with a velocity of 4 m/sec, the force required is
A block of mass 15kg is placed on a long trolley. The coefficient of static friction between the block and the trolley is 0.18. The trolley accelerates from rest with 0.5ms−2 for 20s and then moves with uniform velocity. Discuss the motion of the block as viewed by,
