Question

A horse does a work of 6250 J while applying a force of 250 N in pulling a tonga. The displacement produced in tonga is

• A. 12.5 m
• B. 15 m
• C. 25 m
• D. 20 m

Answer 1

The correct option is C

25 m

Step 1 : Given data:

Work done by horse is W = 6250 J,

Force applied by horse in pulling a tonga is F = 250 N,

To find, Displacement produced by tonga, S

Step 2 : Formula used

1. Work done is defined as the product of force and distance moved in the direction of the force.
2. According to the formulae,
   Work done = Force x Displacement
   $\mathrm{Displacement}=\frac{\mathrm{Work}\mathrm{done}}{\mathrm{Force}}$
   S = $\frac{\mathrm{W}}{\mathrm{F}}$
3. Substituting the known values,
   $\mathrm{S}=\frac{6250\mathrm{J}}{250\mathrm{N}}$ = 25 m

Step 3 : Final answer
Thus, the displacement produced in the tonga is 25 m.

Hence, option (C) is correct.
