Question

Calculate the kinetic energy of a 1158-kg car moving at 55 km/h.

Answer 1

The kinetic energy is 135183.99 J

Step-by-step explanation:

Given that,

Mass = 1158 kg

Velocity = 55 km/h = 15.28 m/s

We need to calculate the kinetic energy

The kinetic energy is equal to the half of the product of the mass and square of velocity.

Using formula of kinetic energy

`K.E=(1)/(2)mv^2`

`K.E=(1)/(2)*1158*15.28^2`

`K.E=135183.99\ J`

Hence, The kinetic energy is 135183.99 J
