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=$\frac{work}{time}$

$power=\frac{force\times distance}{time}$

therefore,

$distance=\frac{power\times time}{force}$

$distance=\frac{150watts\times8s}{15N} \\distance=80m$
