Example 2: **Calculating Momentum 1**

in the correct units!Remember to check the units! //Step 2: Decide how to tackle the problem//What is being asked? We are asked to calculate the ball's momentum. From the definition of momentum,**p** = m**v**,we see that we need the mass and velocity of the ball, which we are given. //Step 3: Do the calculation//We calculate the magnitude of the ball's momentum,p = mv = (3kg)(2ms-1) = 6 kgms-1 //Step 4: Quote the final answer//We quote the answer with the direction of the ball's motion included __**p** = 6 kgms-1 to the right.__ []
 * Question:** A ball of mass 3kg moves at 2ms-1 to the right. Calculate the ball's momentum.**Answer:**//Step 1: Decide what information has been supplied.//The question explicitly gives
 * the ball's mass, and
 * the ball's velocity
