Question 8

From Physics HL Paper 1A (May 2025, TZ2)

  1. A car of total mass M is travelling with a constant speed v. Each of the four wheels of the car has a mass m and a radius R and rolls without slipping.

The moment of inertia of each wheel is I = 1/2 mR².

What is sum of the rotational kinetic energy of all four wheels / translational kinetic energy of the car?

Fractional expression representing the ratio of the sum of rotational kinetic energy of four wheels to the translational kinetic energy of the car, as part of question 8.
