The diagram shows an adult and a child pushing a loaded shopping trolley with a total force of 50 N. They do 4000 J of work pushing the trolley.

Calculate the distance they have pushed the trolley. Show clearly how you work out your answer. Add the units.

A) 40 meters
B) 80 meters
C) 100 meters
D) 200 meters

Answer :

Final answer:

Using the formula for work, which is Work = Force x Distance, we rearranged the formula to find the distance. After plugging in the given values for work and force, we calculated that the trolley was pushed 80 meters.

Explanation:

The subject asked about involves the calculations relating to work, force, and distance, which reside under the domain of physics. Work is calculated by the equation: Work = Force x Distance. From the problem, we know the Work done is 4000J and the Force applied is 50N. To find the Distance we rearrange the equation for Distance: Distance = Work / Force = 4000J / 50N = 80 meters. Therefore, the correct answer is B) 80 meters.
