Question

Calculate the kinetic energy of a car of mass 200 kg which is running with a speed of 10 metre per second. Explain with full sum

Answer 1

Answer:-

Given:-

• Mass of the car = 200 kg
• Speed of the car = 10 m s^-1

To Find:-

Kinetic energy of the car.

___________...

We know,

K.E. = (½) mv²

where,

• K.E. = Kinetic energy,
• m = Mass of the particle &
• v = Velocity. (Consider speed in this case.)

∴ K.E. = ½ (200 kg) (10 m/s)²

➠ K.E. = 100 kg (100 m²/s²)

➠ K.E. = 10000 kg m² s^-2

➠ K.E. = 10000 J

Therefore, the kinetic energy possessed by the car was 10,000 Joules.
