Question

Name: 5. A tow trucks pulls with a 1000 N force a small car, causing it to accelerate. What force does the car exert on the tow truck? r less than 1000 N.b 1000 N. c. more than 1000 N. d. it's not possible to tell. 6. Increasing the mass of an object always increases a, the normal force on the object. b the amount of force required to move the objeet. c. the inertia of the object d. the amount of force required to keep the object moving. For questions 7- 10 refer to the diagram below. A student attaches a bucket to a block. Consider the following forces: 1. The tension force 2. The force of the table on the block up. 3. The force of kinetic friction 4. The force of the earth on the block 5. The force of static friction 7. Which of those forces act on the block if it does not move? a. 1, 2, 3, and 4 b. 1, 2, 4, and 5c.1,2,3, and 5 d.2, 3,4 and 5. 8. Now, the student fills the bucket with water and the block starts to slide at a constant velocity. d. 2, 3, 4 and S Which forces are acting on the block now? a. 1, 2, 3, and 4 b. 1, 2, 4, and 5c. 1, 2, 3, and 5 9. The bucket is now fill with sand to the same label as water. The block will a. moves at constant speed. b. slows down gradually to a stop. c. speeds up for a bit, then moves at constant speed. daccelerates constantly. 10. Eventually, the block reaches the edge of the table. After the block leaves the table, which of the following forces act on the block? a. the force of motion c. kinetic friction b. a normal force d. the force of gravity A 500 N desk is pull across a marble floor at a constant velocity by a 350 N force. What is the coefficient of kinetic friction between the desk and the floor? a. 0.3 b. 0.7 c. 1.43 d. 150

Explanation / Answer

5) according to netwon's third law , every action has equal and opposite reaction

so it will be equal to 1000 N

option b) 1000 N is the correct answer
