Challenge Problems
Push your limits with advanced challenges
A vehicle requires 2000 N of force to maintain its rolling speed on a surface with a rolling friction coefficient of 0.01. Estimate the weight of the vehicle.
💡 Hint: Remember that the normal force relates directly to weight.
Calculate the energy loss per meter due to rolling friction for a wheel where the rolling friction coefficient is 0.005 and the weight is 500 N.
💡 Hint: Use the relationship between friction, weight, and energy.
