Question

A net force of 5 N moves a 2kg object a distance of 3 meters in 3 seconds. How much work is done on the object?

1) 1 J
2) 30 J
3) 10 J
4) 15 J

Answer 1

The work done on a 2 kg object when moved 3 meters by a 5 N force is 15 J, using the work formula W = F × d.

Step-by-step explanation:

The question asks us to calculate the work done on an object when a net force moves it over a certain distance. The formula for work done (W) is W = F × d, where F is the net force and d is the distance moved in the direction of the force. In this case, a net force of 5 N moves a 2 kg object a distance of 3 meters.

Work done can be calculated by multiplying the net force by the displacement in the direction of the force, which gives W = 5 N × 3 m = 15 Joules (J).

Therefore, the correct answer to the amount of work done on the object is 15 J, which corresponds to option 4).
