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?

Respuesta :

Answer:

[tex]3.125\times 10^{5}watt[/tex]

Explanation:

We are given that

Mass of car, m=1500 kg

Acceleration,[tex]a=10m/s^2[/tex]

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

[tex]F=1500\times 10=15000N[/tex]

Work done, W=Fs

Work done, W=[tex]15000\times 1250[/tex]

Power, P=[tex]\frac{work\;done}{time}[/tex]

Using the formula

Power, P=[tex]\frac{15000\times 1250}{60}[/tex]

Power, P=312500watt

Power, P=[tex]3.125\times 10^{5}watt[/tex]
