A car weighing 12kg moving with a speed of 20 m/s2 has a kinetic energy of 2400J
Given
Weight of the car = 12kg
Speed of the car = 20 m/s2
To Find
The kinetic energy of the car
Solution
The kinetic energy (KE) of the car can be calculated using the formula 1/2mv2 where,
m is the mass of the car = 12kg
v is the speed of the car = 20 m/s2
Therefore, kinetic energy = (12 * (20)2)/2 = 2400J
Hence a car weighing 12kg moving with a speed of 20 m/s2 has a kinetic energy of 2400J
