Question

Calculate the kinetic energy of a 1000 kg car traveling at 30 m/s, a typical speed on a highway.

Answer 1

The kinetic energy of the car is $4.5\cdot 10^5 J$

Explanation:

The kinetic energy of an object is the energy possessed by the object due its motion. It is given by

$E_k = \frac{1}{2}mv^2$

where

m is the mass of the object

v is its speed

For the car in this problem, we have:

m = 1000 kg is its mass

v = 30 m/s is its speed

Substituting into the equation, we find the kinetic energy of the car:

$E_k = \frac{1}{2}(1000)(30)^2=4.5\cdot 10^5 J$
