    • Force Practice Problems Show work for the following problems on the back of this sheet! Force Mass Acceleration Answer 1. ? 65 kg 25 m/s2 2. ? 1.2 kg 16 m/s2 3. ? .025 kg 100 m/s2 4. 50 N ? 5 m/s2 5. 100 N 45 kg ? Show all work for the following problems. No credit will be given if you do not show all steps! 6. A car has to come to a quick stop at a red light. In doing so it accelerates at a constant rate of -50 m/s2. If the car has a mass of 2200 kg, what is the force needed to stop the car? 7. An apple falls from a tree. If the apple has a mass of .25 kg, what is the force needed to make the apple fall? (Remember, the acceleration due to gravity is -9.8 m/s2) 8. If it takes 23N of force to push your book off of the table, what is the acceleration of the book if it has a mass of 1.5 kg? 9. If a dog is accelerating at a constant rate of 6.57 m/s2, what is the mass of the dog if 25 N of force is being applied to it? 10. If a 20 kg child started a race and accelerated to a speed of 12 m/s in 6 seconds, what is the force caused by the child running? (Hint: This questions has two parts!) Name: Period: IPC Date:
