Question

A mother used 150 watts of power to raise a 15 newton object in a time interval of 8.0 seconds. Through what vertical distance was the object raised ?

Answer 1

Solution,

In this question we have given,

power of motor=150watts

time=8s,

force=15N

we know that,

power=
`(work)/(time)`

`power=(force* distance)/(time)`

therefore,

`distance=(power* time)/(force)`

`distance=(150watts*8s)/(15N) \\distance=80m`
