Question

ii. A car and a truck have the same speed of 30 m/s .If their
masses are in the ratio of 1:3 find the ratio of their kinetic
energies.​

Answer 1

Explanation:

the velocity of the car = velocity of the truck. We know that kinetic energy = 1/2mv^2. Given that Their mass is in the ratio = 1:3. = 450.
