Question

A car of mass 1000 kg accelerates from rest 100 km per hour in 5 second what is the average power of the car

Answer 1

Hey mate.......here is ur ans...✌❤❤

✔1km = 1000m
1000km = 1000 × 1000 = 1×10^6


✔Average power is defined as work done per unit time
= Work done / time

✔F = mg
F = 1000kg × 10m/s^2
F = 10000N

✔Work done = f × s
= 1×10^6 × 1
= 1×10^6

✔Power = 1×10^6 / 5
Power = 2×10^5


Hope it helps u....thanks....✌❤❤
