1. Show that an impulse of 100 N#s occurs when the same 10-N force acts on the cart for twice the time.

Work W = Fd (where F and d are in same direction)

2. Calculate the work done when a force of 2 N moves a book 3 m.

3. Show that 45 J of work is done when a 15-N force pushes a cart 3 m.

Power = work done/time interval, P = W/t
