Ok thank you. I'll give it another go.

Oh yes the impulse is equal to the change in momentum. I can find the impulse by multiplying the force times the change in time. The momentum is simply P=mv.

well K=1/2mv^2 and P=mv I'm not really sure how to incorporate these into the equation. I'm not really sure about the formula that relates average force to the change in momentum.

1. A pellet gun fires ten 2.0 g pellets per second with a speed of 500 m/s. The pellets are stopped by a rigid wall. What are (a) the magnitude of the momentum of each pellet, (b) the kinetic energy of each pellet, and (c) the magnitude of the average force on the wall from the stream of...
