A block of mass 50 kg is projected horizontal on a rough horizontal floor. The coefficient of friction between the block and the floor is 0.1. The block strikes a light spring of stiffness `k = 100 N//m` with a velocity `2 m//s`, the maximum compression of the spring is

A block of mass 2 kg, initially at rest on a horizontal floor, is now acted upon by a horizontal force of 10 N . The coefficient of friction between the block and the floor is 0.2. If g = 10 m//s^(2) , then :

A block of mass 'm' is pulled by a constant power 'p' placed on a rough horizontal plane . The coefficient of friction between the block and the surface is mu . Maximum velocity of the block will be

A block of mass 0.18 kg is attached to a spring of force-constant 2 N//m . The coefficient of friction between the block and the floor is 0.1 Initially the block is at rest and the spring is un-stretched. An impulse is given to the block as shown in the figure. The block slides a distance of 0.06 m and comes to rest for the first time. The initial velocity of the block in m//s is V = N//10 . Then N is : .
