@ tcdsb.elearningontario.ca = e (C) PROBLEM SET 3.2 Submit completed work at least 15 min before the start of next class Work each of the following problems. SHOW ALL WORK. 1. Which object would have more inertia - a 1000 kg car travelling 2 m/s or a 150 kg golf cart travelling 50 m/s? Explain your answer. An object experiences a certain net force that causes a certain acceleration. If the net force on the object is tripled, what happens to the acceleration of the object? Abox is being pulled across a horizontal surface by a 20 N force to the right. a) I the box moves at a constant velocity, what do you know about the forces acting on the object? b) If the box moves at a constant velocity, how much force opposes the motion of the box? ) Ifthe box experiences a force of 15 N to the left, along with the 20 N force acting to the right, what is the net force on the box? 4. Abaseball bat can apply a force upwards of 18000 N on a ball. How much force does the ball apply on the bat? 5. A25 kg block is pulled with an applied force of 200 N across a horizontal surface. The block experiences a frictional force of 75 N. . Draw a free-body diagram for the block, including allforces acting on the block. b. Determine the net force acting on the block. . Calculate the acceleration of the block. @ tcdsb.elearningontario.ca R 6. AA40 N force is applied to a 10kg block, but the object only accelerates at 2 m/sA2. Explain why this happens using a FBD. 7. Afootball blocking sled has a mass of roughly 100 kg. If a football player applies a force of 500 N to the sled, and there is a 350 N frictional force acting on the sled, what is the acceleration of the sled? Be sure to draw a free-body diagram. 8. A 1000 kg elevator is accelerated upward at a rate of 0.70 m/s%. What is the tension in the cable pulling the elevator upward when it experiences this acceleration? Be sure to draw a free-body diagram
