a block of mass 2.5kg moving with speed v on a horizontal surface collides with a horizontal spring of negligible mass ang spring constant 320N/m. The block compresses the spring by 8.5cm from its equilibrium position. if the coefficient of friction between the block and the floor is 0.40, what is the speed of the block just before collision?
