1.

2.

3.

4. Practice Problems:

1. A man hits a golf ball (0.2 kg) which accelerates at a rate of 20 m/s2. What amount

of force acted on the ball?

2. You give a shopping cart a shove down the aisle. The cart is full of groceries and

has a mass of 18 kg. The cart accelerates at a rate of 3 m/s2. How much force did

you exert on the cart?

3. You push a friend sitting on a swing. She has a mass of 50 kg and accelerates at a

rate of 4 m/s2. Find the force you exerted.

4. How much force would it take to push another, larger friend who has a mass of 70

kg to accelerate at the same rate of 4 m/s2?

5. If a car travels at 400m in 20 seconds how fast is it going?

6. While drag racing out of our school parking lot, I time myself at a speed of 40 meters per second seven seconds after starting. What was my acceleration during this time?

7. In a competition, an athlete threw a ball 139 meters through the air. While in flight the ball traveled an average speed of 13.0m/s. How long was the ball in air?

8. Sally has a car that accelerates at 5 m/s2. If the car has a mass of 1000 kg, how much force does the car produce?

9. What is the mass of a truck if it produces a force of 14,000 N while accelerating at a rate of 5 m/s2 ?

10. What is the average speed of a car that traveled 300.0 miles in 5.5 hours

11. Calculate the acceleration of a bus whose speed changes from 6 m/s to 12 m/s over a period of 3s.

12. A cyclist accelerates from 0 m/s to 8 m/s in 3 seconds. What is his acceleration ? Is this

acceleration higher than that of a car which accelerates from 0 to 30 m/s in 8 seconds?

13. A car advertisement states that a certain car can accelerate from rest to 70 km/h in 7 seconds. Find the car’s average acceleration.
