Question

How much work would a child do while pulling a 12-kg wagon a distance of 4.3 m with a 22 n force?

Answer 1

Answer:

Work:

"Work is distance,d traveled in the direction of the force,F which is applied to it."

Formula:

• W=F.D, or we can place "s" instead of the "D".

So, now we have the data provided in the problem, as we have the;

• mass,m= 12 kg,
• distance,D=4.3 m,
• force,F= 22 N.

Solution:

As putting the values inside the given formula;

• W=(22).(4.3),
• W=94.6 J(joules).⇒ The Answer.

Answer 2

The work done by the child while pulling the wagon is given by:

$W=Fd$

where F is the force applied and d is the distance through which the wagon has been moved.

In this problem, F=22 N and d=4.3 m, therefore the work done by the child is

$W=Fd=(22 N)(4.3 m)=94.6 J$
