A 0.20kg hockey puck is initially at rest on frictionless ice. It is struck by a stick so that the net horizontal force rises linearly from zero to a peak value Fpeak in 5.0×10−2s and then falls linearly back to zero in the next 5.0×10−2s. Immediately after the force pulse ends, the puck slides at 3.0ms−1. What is Fpeak?
a) 30N
b) 12N
c) 6.0N
d) 24N
