Force Simulation Make-Up Assignment

Directions: On a piece of paper, please answer the following questions using the equation:   FORCE = MASS x ACCELERATION

Plug in the given values for Force/Mass/Acceleration to solve.

Remember, mass is in kg - - force in in N (newtons) - - acceleration is in m/s2

1. How much force is needed to accelerate a 66 kg skier at 2 m/sec2?

2. What is the force on a 1000 kg elevator that is falling freely at 9.8 m/sec2?

3. What is the acceleration of a 50 kg object pushed with a force of 500 newtons?

4. The mass of a large car is 1000 kg.  How much force would be required to accelerate the car at a rate of 3 m/sec2?

5. A 50 kg skater pushed by a friend accelerates 5 m/sec2.  How much force did the friend apply?

6. A force of 250 N is applied to an object that accelerates at a rate of 5 m/sec2.  What is the mass of the object?

7. A bowling ball rolled with a force of 15 N accelerates at a rate of 3 m/sec2; a second ball rolled with the same force accelerates 4 m/sec2.  What are the masses of the two balls?

8. If a 60 kg person on a 15 kg sled is pushed with a force of 300 N, what will be person’s acceleration?
