A student lifts a backpack with a force of 50 Newtons. She lifts the backpack 2 meters off the floor. Calculate the work that she has done.
work= forceinNewtons*distanceinMeters
I hope this answers your question!!
To calculate the work done, we can use the formula:
Work = Force × Distance
In this case, the force is 50 Newtons and the distance is 2 meters. So, we can substitute these values into the formula:
Work = 50 N × 2 m
Multiplying the numbers:
Work = 100 N·m
The unit for work is joules (J), so we can also write the answer as:
Work = 100 J
Therefore, the student has done 100 joules of work by lifting the backpack.
