1 kg block collides with a horizontal massless spring of force constant `2 N//m`. The  block compresses the spring by 4m. If the coefficient of kinetic friction between the block and the· surface is 0.25, what was the speed of the block at the instant of collision? (take `g = 10 m//s^(2)`) img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/EAM_MEC_V01_C03_E01_020_Q01.png" width="80%"
