1. The problem statement, all variables and given/known data A ball of mass 0.4 kg is initially at rest on the ground. It is kicked and leaves the kicker’s foot with a speed of 5.0 m/s in a direction 60◦ above the horizontal. The magnitude of the impulse k~Ik imparted by the ball to the foot is most nearly 3. The attempt at a solution I=change(p) pf-pi mvf-mvi (0.4)(5cos60)-(0.4)(0) =1 N*s Where did I go wrong in the problem?
