Question 7
A 1.0 kg block collides with a horizontal weightless spring of force constant 2.75 Nm–1 as shown in figure. The block compresses the spring 4.0 m from the rest position. If the coefficient of kinetic friction between the block and horizontal surface is 0.25, the speed of the block at the instant of collision is
