Question

Two cars of different masses have same kinetic energy, then

• A. Heavier car has more linear momentum
• B. Heavier car has less linear momentum
• C. Both cars have same linear momentum
• D.

Hint:

In problems involving kinetic energy, the linear momentum increases with the mass of the object if the kinetic energy is the same.

Answer 1

The Correct Option is A

Since the two cars have the same kinetic energy, we can use the formula for kinetic energy: \[ K.E. = \frac{1}{2} m v^2 \] From this, the velocity of each car can be calculated. The linear momentum \( p = mv \) is directly proportional to the mass of the car, meaning the heavier car will have more momentum.
