Question

If a small motor does 520 J of work to move a toy car 260 m, what force does it exert

Answer 1

Answer:

Force, F = 2 N

Explanation:

It is given that,

Work done by the small motor, W = 520 J

Distance covered by small motor, d = 260 m

The work done is given by the product of force and distance. It is mathematically, equal to :

$W=force\times distance$

$Force=\dfrac{work}{distance}$

$Force=\dfrac{520}{260}$

Force, F = 2 N

Hence, the force exerted to the small motor is 2 N.

Answer 2

$Work done = Force\times distance$

From the question,

work done is 520 J

Distance is 260 m

This implies that,

$520 =F\times260$

$F=\frac{520}{260}$

$F=2N$

Hence the motor exerts a force of 2N .
