Answer 1

Question#18728

a body of mass 5kg is displaced through a distance of 2m with uniform acceleration of 3ms-2 calculate work done

Solution:

The done work is:

$A = FS$ , were $F$ - force due to the body, $S$ - displacement

According to the Second Newton's Law:

$F = ma,$ were $m - mass, a -$ acceleration

$$A = m a S = 5 * 3 * 2 = 3 0 J$$

Answer: 30 J
