70. 158,400 N F= m x a

71. A dock worker needs to stop a crate containing 3 boxes of goods that is rolling across a manual conveyer belt. One box has a mass of 8.5kg and is accelerating at.75m/s 2. How much force will he need to apply to the crate in order to stop it?

72. 19.125 N The crate contains 3 boxes so you must multiply the mass of one box by 3 to get the mass of the entire crate. (3 x 8.5 kg= 25.5 kg) Use the formula f=m x a F= 25.5kg x 0.75 m/s 2 = 19.125N

73. When you are riding in a car and you must come to a complete stop abruptly, why does you body continue to move forward?
