Question

A 200-kg car is moving at 50 mis. What is the kinetic energy of the car? show

Answer 1

Ekin = 250000 [J]

Step-by-step explanation:

The kinetic energy of a body or object can be calculated based on the mass and the speed with which it moves. This energy can be easily calculated by means of the following equation.

`E_(kin)=(1)/(2) *m*v^(2)`

where:

m = mass = 200 [kg]

v = velocity = 50 [m/s]

Now replacing:

`E_(kin)=(1)/(2) *200*(50)^(2)\\E_(kin)=250000[J]`
