Types of Force 1. The cube in the free body diagram to the right represents an object moving with a constant velocity of 15 m/s. Sketch in any forces that may be missing. 8N 2. If the net force on a block is zero, then acceleration is 3. Objects with more mass have less inertia. True or False 5N 4. Inertia is the tendency of an object at rest to stay at rest. True or False 5. Inertia is the tendency of an object in motion to stay in motion. True or False 6. The object shown above is moving upward with a speed of 25 m/s. There are constant forces acting on it, shown on the free-body diagram. The net force is 7. A certain motor can produce a force of 70 N on a model plane. If the required acceleration is 30 m/s?, then what is the maximum mass the plane can have? 8. A car has a mass of 2,000 kg. How much force is required to stop the car in 4.0 seconds from a speed of 20 m/s? 9. What is the acceleration of a 100 kg object that experiences a net force of -10 N? 10. A 3.25kg cart accelerates from rest to 30 m/s in 6.0 seconds. What is the net force on the car? 11. What is the force of friction between a block of ice that weighs 950 N and the ground if u = 0.12? 12. What is the coefficient of static friction if it takes 35 N of force to move a box that weighs 67 N
