Question

A hydraulic system at the mechanic shop can perform up to 180,000 joules of work in a day. if throughout the day it can lift 10 cars from the ground to a height of 2 meters, how much can the cars each weigh in Newtons?

Answer 1

9,000 N.

Step-by-step explanation:

Workdone can be defined as the ability to do work. It is also the product of the force and the distance it is being moved.

Mathematically,

W = F * d

= 180,000/2

= 90,000 N.

Weight of the 10 cars = 90,000 N.

Weight of a car = 90000/10

= 9,000N.
