Question

What force should an engine develop, so that it causes a displacement of vehicle through 100 m, such that work done by it is 0.50 mega joule?

Answer 1

Given:

Displacement (S) = 100 m

Work Done (W) = 0.50 mega joule (MJ)

Converting Work Done into standard S.I. units (Joules):

W = 0.50 × 10⁶ J

= 5,00,000 J

Formula:

Work Done (W) = Force (F) × Displacement (S)

\[ F = \frac{W}{S} \]

\[ = \frac{5{,}00{,}000\ \text{J}}{100\ \text{m}} \]

= 5000 N
