Answer:
<u>666.6 kW</u>
Explanation:
<u>Power Formula</u>
<u>Calculating Force</u>
- F = ma
- F = m(v - u / t) [From the equation v = u + at]
- F = 2,000 (50/7.5)
- F = 2,000 (20/3)
- F = 40,000/3
- F = 13333.3 N
<u>Solving for Power</u>
- P = 13333.3 × 50
- P = 666666.6 W
- P = <u>666.6 kW</u>
The answer is A
