FORCE PROBLEMS 1. 2. 3. 4. 5. 6. 7. 8. Show three ways to arrange the force equation. Calculate the force required to accelerate a 80kg go cart at 3.0m/s2. Determine the force necessary to accelerate a 3000kg rocket at 15.00m/s2. What force is required to accelerate a 2000kg truck at 3.0m/s2? What is the forward acceleration of a 2000kg truck when the tires apply an accelerating force of 234N to the road? In the last question, in which direction must the tires apply the accelerating force? In question 6, which of Newtonâ€™s three laws helps you answer the question? Whet is the net force acting on the box shown below? 9. What is the acceleration of the box shown in the diagram above? 10. How much net force would be required to accelerate the box in question 8 at 3.0m/s/s? 11. What is the net force acting on the box shown in the diagram below? 12. Refer back to the box in question 11. What is the acceleration of the box? 13. Refer back to the box in question 11. Which of the following could possibly be the velocity of the box? A. 8.5m/s B. 2.2m/s C. 16m/s D. 0m/s 14. What is the mass of a cannon projectile that is accelerated at 220m/s/s by a 2000N force? 15. What is the mass of a cart that is accelerated at 4.0m/s/s by an applied force of 330N? 16. During an accident, a 85kg body slows from 10m/s to 0m/s in 3.0s. A. What is the acceleration of the body? B. What is the force experienced by the body? 17. Determine the net force for each of the following objects? A.________ D.__________ B._________ C._______ E. _________ 18. Convert 600Newtons to kgm/s2. 19. The rocket engine of a 40kg rocket apply a thrust force of 8000N to the rocket. What is the acceleration of the rocket? 20. Refer back to question 19. Draw a diagram of the rocket. Label each of the following. Rocket mass, acceleration, thrust force, action force, reaction force, rocket weight. ( Any force must be indicated using a labeled arrow to show the size of the force and direction of the force.) 21. Mr D. has a mass of 80Kg. How much does he weigh? 22. Calculate your own weight in Newtons. ( Starting point Hint: 1 kilogram is 2.2 pounds.)
