# Work calculations

## Stage 1

Calculate the work done for the following:

1. A 29 N force moves an object 44 m.

2. An object with a weight of 44 N is raised through a height of 1 m.

3. A cyclist brakes with a braking force of 180 N and it takes her 13.5 m to come to a stop.

4. A car with a braking force of 1200 N travels a distance of 330 m before coming to a stop when the brakes are applied.

5. A ball thrown with a force of 140 N travels 5.4 m.

## Stage 2

6. Find the distance an object is moved when 6 J are transferred using a force of 2 N

7. Find the force when a car travels a distance of 540 m before coming to a stop when 1026000 J of energy are transferred.

8. Find the distance travelled when a cyclist brakes with a 160 N force before coming to a stop when 336 J are transferred.

9. Find the distance a ball travels when thrown using a 80 N force and 904 J of work is done.

10. Find the distance a car travels when 1900 N braking force transfers 741000 J of energy to bring the car to a stop.

## Stage 3

11. Find the distance a ball travels when thrown using a 140 N force and 0.002198 MJ are transferred.

12. Find the distance when a 46 N force does 1840 J of work to move an object.

13. Find the energy transferred when an object moves 28 m when a 0.04 kN force is applied.

14. Find the work done when a ball travels 0.0019 km when thrown with a force of 50 N.

15. Find the force used to throw a ball 1550 cm using 1705 J.
