Q. A snowboarder is pulled by a tow rope along a horizontal surface with a constant force of 60 N. How far must the boarder be pulled, starting from rest, so that her final kinetic energy is 500 J?

Q. A 0.344 kg block is attached to a horizontal spring that is at its equilibrium length, and whose force constant is 22.6N/m. The block rests on a frictionless surface. A 0.0500 kg wad of putty is thrown horizontally at the block, hitting it with an initial speed of 1.86 m/s and sticking. How far does the putty-block system compress the spring?
