Question

What is the value of work done on an object when a 70–newton force moves it 9.0 meters in the same direction as the force?

A.
7.8 joules
B.
6.3 × 102 joules
C.
-7.8 joules
D.
0 joules

Answer 1

The work done by the force is $6.3\times10^{2}\ J$

(B) is correct option.

Explanation:

Given that,

Force = 70 N

Distance = 9.0 m

We need to calculate the work done by the force

Using formula of work done

$W=F\cdot d$

Where, F = force

d = distance

Put the value into the formula

$W=70\times9.0$

$W=630\ J$

$W=6.3\times10^{2}\ J$

Hence, The work done by the force is $6.3\times10^{2}\ J$
