Question

7.

Joe carried a carton of milk, weight 10 N, along a level hall to the kitchen, a distance of 3.5 m.
How much work did Joe do?

Answer 1

Work is defined as force multiplied by distance, and it is measured in joules (J). In this case, the force that Joe is exerting on the carton of milk is 10 N and the distance he is moving it is 3.5 m. Therefore, the amount of work that Joe does can be calculated using the formula:

work = force x distance

So,

work = 10 N x 3.5 m = 35 J

Joe does 35 joules of work by carrying the carton of milk.
