A 1.3 kg block rests on a horizontal plane, compressing a recovery spring of 100 N / m by 20 cm. When the block is released, it advances on the plane until it stops. Taking into account that the coefficient of kinetic friction between the block and the plane is 0.30. Decide:
a) The speed with which the block leaves the spring.
b) The total distance traveled by the block on the plane to stop.
