Question

A 1500kg car is moving uniformly at 10 m/s2 down the road for 1250 meters in 60 seconds. How much power did the car have during this time?

Answer 1

`3.125* 10^(5)watt`

Step-by-step explanation:

We are given that

Mass of car, m=1500 kg

Acceleration,
`a=10m/s^2`

Distance, s=1250 m

Time, t=60s

We have to find the power of car during this time.

We know that

Force, F=ma

Using the formula

`F=1500* 10=15000N`

Work done, W=Fs

Work done, W=
`15000* 1250`

Power, P=
`(work\;done)/(time)`

Using the formula

Power, P=
`(15000* 1250)/(60)`

Power, P=312500watt

Power, P=
`3.125* 10^(5)watt`
