Makayla applied a force of 90N to move a crate a distance of 4meters. How much work has been done?
A: 22.5J
B: 86 J
C: 94 J
D: 360 J
D. 360 J
You multiply force 90N x 4 meters = 360.
To calculate the amount of work done, you need to multiply the applied force (in newtons) by the distance moved (in meters). In this case, Makayla applied a force of 90N to move the crate a distance of 4 meters.
The formula for work is:
Work = Force × Distance
Therefore, the work done can be calculated as:
Work = 90N × 4m
Work = 360 N·m
Now, you need to convert the unit of work from N·m (newton-meters) to joules (J). Since 1 joule is equal to 1 newton-meter, the work done is equal to 360J.
Therefore, the answer is D: 360 J.
