Practice the following problem sets completely. Show solutions please.

1. A vehicle is accelerating at a rate of 1.20 m/s². If the net force is tripled and the mass is halved, what is the new acceleration of the vehicle?
2. A 1,800.00-kg car uniformly accelerates for 12.50 s from rest. During this time, the car travels 145 m, north. What is the net force acting on the car during this acceleration?
3. A 3,500.00-kg truck accelerates uniformly from 15.00 m/s east to 35.00 m/s east. During this acceleration, the truck travels 187.00 m. what is the net force acting on the car during this acceleration?
4. A horizontal force of 30.00 N is applied to a 60.00-kg grocery cart on a level floor.

• How far will it move in 5.00 s, starting from rest? Ignore friction.
• How far will it move in 5.00 s if 20.00 N of groceries are added to the grocery car first?

5. A box resting on a table has a mass of 5.0 kg.

• What is its weight?
• What will be its acceleration when an unbalanced horizontal force of 40N acts on it?

6. What is the weight of an object that has a mass of 60 slugs?

7. A net force of 75 pounds acts on a body of 25 slugs. The body is initially at rest. What is its acceleration during the action of the force?

8. What is the mass of a 185 pound man? If a 100 pound horizontal net force acts on the man while he is sitting on a wooden floor, what will be his acceleration
