Question

how far can a mother push a baby carrier using a force of 62 N if she can only do 2,920 J of work

Answer 1

Answer:

A mother can push the baby carrier 47.1 m far.

Explanation:

What does it mean to do work in physics?

Work is the mechanical means of transferring energy. To do work you must follow two rules:

1. you have to push (exert a force) on a object;
2. this object must move a distance in the direction of that force.

Now let's solve this problem by writing the data down:

$F= 62\,N\\\\W=2,920\,J\\\\d=?$

I can solve this by applying the formula:

$work=force \times distance\\\\W=F\times d$

Plug the given data in the formula, we'll get:

$2,920=62\times d$

Divide both sides by 62:

$\dfrac{2,920}{62}=\dfrac{62}{62}\times d$

Therefore:

$\boxed{d \approx 47.1\,m}$

Answer: a mother can push a baby carrier  47.1 m exerting a force of 62 N.
