A Newton`s 2nd Law
... (7 marks) 2. A particle P of mass 4 kg moves in a horizontal plane under the action of a constant force (2i – 8j) N. 6 seconds after the force starts acting, the velocity of P is (3i + 7j) ms-1. a) Find the velocity vector of P when the force starts acting. (4 marks) b) Find the time that has elapse ...

10.4 Newton`s Third Law of Motion and Momentum
... Momentum vs. Inertia • Momentum is a measurable vector quantity (product of mass and velocity) • Inertia is dependent on mass, but it is an object’s resistance to a change in velocity What has more momentum: a 200 pound man running at 1 mph or a 65 pound girl running at 4 mph? Why? ...
