A block of mass `2 kg` is placed on an inclined plane of angle `53^@`, attached with a spring as shown. Friction coefficient between block and the incline is `0.25`. The block is released from the rest and when spring is in natural length. Find maximum speed of the block it acquires after the release in cm//s is found to be nearly `5n`. Find `'n'(take g = 10 m//s^(2))`.
