<em>weight = (mass) x (gravity)</em>
Weight = (5.00 kg) x (9.81 m/s²)
weight = (5.00 x 9.81) (kg-m/s²)
<em>Weight = 49.05 Newton</em>

The potential energy in the spring is given by:
where k is the spring constant and x is the compression of the spring.
The work done by friction is given by:
where s is the sliding distance, N the normal force N = mg, m is the mass of the block, g is the gravitational acceleration and μ is the coefficient of dynamic friction.
The work done by friction must be equal to the energy provided by the spring:
