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

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

Step-by-step explanation:

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

`\sf \displaystyle P=(3 * 10 * 50 )/(15)`

`\sf \displaystyle P=(1500 )/(15)`

`\sf \displaystyle P=100`

Answer 2

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

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