1.	A springof spring constant 500 N/m is attached on a rough surface at one side . Coefficient of friction for rough surface is 0.75. A block of mass 100 kg collide with the free end of spring at a speed of 10sqrt(2) ms^(-1), then how much will spring be compressed ? (g =10 ms^(-2))
Answer» SOLUTION :X = 5M
