Answer:-
Given:
Force applied (F) = 2000 N
Displacement / distance (S) = 10 m
Time taken (t) = 50 s.
We know that,
Power (P) = Work done/time taken.
And,
Work done = F * S
So,
⟹ P = (2000) * (10) / 50
⟹ P = 400 Watts
Therefore, the power of the bull is 400 Watts.
Additional Information:
- Power is simply defined as the work done in a unit of time.
- Power = W/t.
- It's S.I unit is J/s or Watt.
- It's C.G.S unit is erg/s.
- Power is a scalar Quantity since it has no direction.

Given:
- Force applied =F = 2000 N
- Displacement / distance =S= 10 m
- Time taken =t = 50 s.
━━━━━━━━━━━━━━━━━
Need to Find:
- The power =?
━━━━━━━━━━━━━━━━━
Solution:
- Work done = F.S
- Power = W ÷ T
━━━━━━━━━━━━━━━━━
Work done
= 2000 × 10 J
= 20,000 J
━━━━━━━━━━
Power = Work done ÷ Time
⟹ P = 20,000÷ 50 watt
⟹
