Challenge Problems
Push your limits with challenges.
Question 1
A truck weighing 2000 kg experiences a constant friction force of 500 N while trying to accelerate to 15 m/s in 5 seconds. Determine the net force required for this acceleration.
💡 Hint: Use F=ma and remember to account for resistance forces.
Question 2
Two cars have different masses: car A (1500 kg) and car B (1200 kg). Both cars accelerate from rest to 25 m/s in 10 seconds. Compare their required net forces and efficiency in energy conversion if car A uses a standard combustion engine and car B is electric.
💡 Hint: Calculate the forces and consider characteristics of energy conversion.
