Question

PLEASE HEP FAST PLEASE!!!!! IM SO SCARED!!!! An elevator has the mass of 3 tons of power needed to raise the elevator 50m in 15 s?

Answer 1

Answer:

Mass=3,height=50 and time=15,g=10,P=?

P=mgh/t....which is 3×10×50=1500/15=100Watts

Answer 2

Answer:

$\huge \boxed{\mathrm{100 \ Watts}}$

Explanation:

$\sf \displaystyle P=\frac{mgh }{t} \\\\\\ P=power \ (W) \\\\ m=mass \ (kg) \\\\ g=gravity \ acceleration \ (m/s^2) \\\\ h=height \ (m) \\\\ t=time \ taken \ (s)$

$\sf \displaystyle P=\frac{3 \times 10 \times 50 }{15}$

$\sf \displaystyle P=\frac{1500 }{15}$

$\sf \displaystyle P=100$
