Question

Calculate the Ek of a car which has a mass of 1000 kg and is moving at the rate of 20 m/s

Answer 1

The kinetic energy of the car is $2.0\cdot 10^5 J$

Step-by-step explanation:

The kinetic energy of an object is the energy possessed by an object due to its motion. Mathematically, 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 the mass of the car

v = 20 m/s is its speed

Substituting into the equation, we find its kinetic energy:

$E_k = \frac{1}{2}mv^2 = \frac{1}{2}(1000)(20)^2=2.0\cdot 10^5 J$
