Ch. 3 Math Problems

Math Problems


1. If a giant hippo pushed a box that had a mass of kg which caused the box to accelerate at a rate of m/s2, then how much force did the giant hippo use?

2. If a wrecking ball hit a brick wall with a force of N which caused the box to accelerate at a rate of m/s2, then how much mass did the brick wall have?

3. If a young boy pulled a wagon filled with toys that had a mass of kg which caused the box to accelerate at a rate of m/s2. If the boy pulled with the exact same force on an empty wagon with a mass of kg, then how fast would the empty wagon accelerate?


4. If a motorboat that had a mass of kg was traveling at m/s, then how much force would be required to stop the boat in s?


If a large shopping cart full of groceries had a mass of kg was traveling down the aisle at a speed of m/s, then how much momentum, did the shopping cart have?

A remote controlled car with a mass of kg was traveling around a track, when it hit the wall. When it hit the wall, it had a momentum of kg-m/s. How fast was the car traveling?
