As an automotive engineer tasked with decreasing each car wheel's angular momentum by 30% while changing the wheel diameter, what considerations should you make?
a) Calculate the new rotational inertia with the revised wheel diameter.
b) Assess the impact of decreased angular momentum on the car's performance.
c) Determine the percentage change in rotational inertia with the diameter reduction.
d) Evaluate the relationship between linear speed and angular momentum.
