Challenge Problems
Push your limits with challenges.
Question 1
A train is moving at a constant speed but suddenly accelerates while making a turn. Discuss how the passengers perceive forces acting on them using the concept of pseudo-forces.
💡 Hint: Think about how forces are perceived versus actual forces acting upon the train.
Question 2
Use the five-term acceleration formula to analyze a particle at the edge of a rotating disk with a radius of 2 meters at a speed of 3 m/s, with an angular acceleration of 0.5 rad/s².
💡 Hint: Split down the formula into parts for clarity.
