Force and Acceleration

Acceleration = Final velocity – Initial velocity Time = Final Velocity – Initial Velocity

Time Acceleration

Final Velocity = Acceleration * Time + Initial Velocity Force = mass x acceleration

Instructions:

1) In order to receive credit for this worksheet you MUST show your work.

2) You MUST write the applicable formula for each problem to receive credit.

3) You can use a calculator but you must show all of the steps.

4) You only need to complete any 10 problems.

1. A roller coaster car rapidly picks up speed as it rolls down a slope. As it starts down the slope, its speed is 4 m/s. But 3 seconds later, at the bottom of the slope, its speed is 22 m/s. What is its average acceleration?

2. 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?

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

4. If a Ferrari, with an initial velocity of 10 m/s, accelerates at a rate of 50 m/s/s for 3 seconds, what will its final velocity be?

5. 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?

6. You give a shopping cart a shove down the isle. 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?

7. The wind pushes a paper cup along the sand at a beach. The cup has a mass of 25 kg and accelerates at a rate of 5 m/s2. How much force is the wind exerting on the cup?

8. 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.

9. 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?

10. A worker drops his hammer off the roof of a house. The hammer has a mass of 9 kg, and gravity accelerates it at the usual 9.8 m/s2. How much force does the earth apply to the hammer?

11. Your bicycle has a mass of 9.1 kilograms. You accelerate at a rate of 1.79 m/s2. Calculate the net force that is accelerating the bicycle.

12. A runner has a mass of 89 kilograms. He produces a force of 84 Newtons between the ground and his running shoes. How fast does he accelerate?

13. The Space Shuttle has a liftoff mass of 2,041,000 kg and accelerates at a rate of 16 m/s2. Calculate the force (thrust) accelerating the Space Shuttle.
