MCQ
A truck of mass $10,000\, kg$ moves up an inclined plane rising $1$ in $50$ with a speed of $36\, km/h$. Find the power of engine .................. $\mathrm{kW}$ $(g = 10\, m/s^2$)
- ✓$20$
- B$30$
- C$40$
- D$60$
✓
Answer
Correct option: A.
$20$
a
Power $P=m g V \sin \theta$
Power $P=m g V \sin \theta$
Putting all the values in the equation will get,
$P=10000 \times 10 \times \frac{1}{50} \times 36 \times \frac{5}{18}=20 k W$
