A brick of weight 40N is lifted up a distance of 0.5m
I don't mind helping to find answers, but I resent having to provide the questions as well.
To solve this problem, we need to calculate the work done to lift the brick.
The work done (W) is given by the formula:
W = force x distance
In this case, the force is the weight of the brick, which is given as 40N, and the distance is 0.5m.
So, the work done to lift the brick is:
W = 40N x 0.5m
W = 20 Joules
Therefore, the work done to lift the brick is 20 Joules.
