Question

A 2.97 kg block initially at rest is pulled to the right along a horizontal surface by a constant, horizontal force of 12.9 N. The coeﬃcient of
kinetic friction is 0.126. The acceleration of gravity is 9.8 m/s^2.
Find the speed of the block after it has
moved 2.92 m.

What equation should we use or what? Thanks
