Create a story problem for momentum. Solve it, showing the formula and the steps involved.

. A condition of the law of conservation of momentum is that no external forces are at play. Look at each of the following situations and determine if the law applies or does not apply. Law does apply. Law does not apply.   ______ A bullet strikes a wooden block causing the block to accelerate from rest. ______ Two cars collide on a dirt road where the force of friction is high. ______ A coin sliding on a table experiences a frictional force. ______ Two kinetic carts collide on a frictionless surface.

The law of conservation of momentum states that_. Choose the letter of the correct answer   a. p before is less than p after   b. p before is more than p after   c. p before is the same as p after   d. all of the choices
