Chapter 7: Problem 53

Find the work done in pushing a car along a level road from point \(A\) to point \(B, 80\) feet from \(A,\) while exerting a constant force of 95 pounds. Round to the nearest foot-pound.

Short Answer

Expert verified
The work done in pushing the car along a level road from point \(A\) to point \(B\) is 7600 foot-pounds

Step by step solution

01

Identify the given values

The force exerted to push the car is constant at 95 pounds. The distance the car is moved is 80 feet.
02

Apply the formula for work

The formula for work done (W) is \(W = Fd\), where 'F' is the force and 'd' is the distance. In this case, \(F = 95\) pounds and \(d = 80\) feet. Thus substituting these values we get \(W = 95 * 80\).
03

Calculate the work done

Upon computation, \(W = 7600\) foot-pounds. Rounding it to the nearest foot-pound, we get 7600 as the work done.
