Question

A car of mass 1000kg accelarates from rest to a speed of 10m/s. what's its power?​

Answer 1

Answer: the power of the car is 50000 watt

Explanation: the mass of the car = 1000 kg

speed of the car = 10 m/s

then, power = 1/2 mass *( velocity)^2

power = 1/2* 1000 kg* (10 m/sec)^2

= 50000 joule/sec ...........(joule= kg* m^2 /sec^2)
