    5.) Weight of a man who is throwing a bag of potatoes?

    7/8) Net acceleration of a body on a curved path

    10) Kinetic energy of a rocket after firing its engine

    14) Acceleration of a point on a wheel

    18) kinetic enregy expressed in terms of momentum

    19) distance traveled & energy lost by skier

    20) escape speed for spacecraft

    21) tension and agular speed of a rock on a string

    22) trajectories after a football tackle

    23) power wasted by falling water
