Answer:
1235.5J
Explanation:
Given parameters:
Mass of car = 2413kg
Speed of car = 32m/s
Unknown:
Amount of kinetic energy it has = ?
Solution:
Kinetic energy is the energy due to the motion of a body;
Kinetic energy = m v²
m is the mass
v is the velocity
Now insert the parameters;
Kinetic energy = x 2413 x 32² = 1235.5J
