Given : A car of mass 1000 kg is moving with a velocity of 4 m/s
To Find : Power of the car after 16 sec
Solution:
Energy = Power x Time
=> Power = Energy / Time
Energy = (1/2)mv²
m = 1000 kg
v = 4 m/s
Energy = (1/2)1000 * 4² = 8000 J
Time = 16 s
Power = 8000/16 J/s
= 500 W
power of the car = = 500 W

calculate the power of the car after 16 seconds in si unit
Energy = power×time
power = energy/time
energy= (1/2)mv
m= 1000 kg
v= 4m/s
energy = (1/2)1000×4²
= 8000 j
time = 16 s
so ,
power = ENERGY/TIME
= 8000/16 watt
= 500 Watt
