1. An object with initial momentum +5.00 kg m/s experiences a net force of +20.0 N for a duration of 1.50 seconds. (a) Determine the net impulse. (b) Determine the object's momentum at the end of the 1.50 seconds.

2. A nearly identical graph is shown for the net force acting on the same 4-kg object. Only this time it shows a force actingas a function of time.The object starts with a speed of 2 m/s again.

Net Force (Newtons) 40 2 10
