When kicking a football, the kicker rotates his leg about the hip joint. (a) if the velocity of the tip of the kicker’s shoe is 35.0 m/s and the hip joint is 1.05 m from the tip of the shoe, what is the shoe tip’s angular velocity? (b) the shoe is in contact with the initially stationary 0.500 kg football for 20.0 ms. what average force is exerted on the football to give it a velocity of 20.0 m/s? (c) find the maximum range of the football, neglecting air resistance.

Aproton is projected toward a fixed nucleus of charge +ze with velocity vo. initially the two particles are very far apart. when the proton is a distance r from the nucleus its velocity has decreased to 1/2vo. how far from the nucleus will the proton be when its velocity has dropped to 1/4vo?

Aperson standing in a canoe exerts a force of 700 n to throw an anchor over the side. find the acceleration of the canoe if the total mass of the canoe and the person is 100 kg?
