What is the force on the block by the spring

Reference no: EM13497385

A spring with constant k = 10 N/m is attached to a block. The other end of the spring is pulled by a motorized toy train that moves forward at a constant speed. There is friction between the block and the surface. The spring is initially unstretched.

What is the force on the block by the spring when the spring has been stretched by 0.05 m?
