Q 1. A 0.645 kg toy train engine is travelling around a horizontal circular track. The track has a radius of 0.790 m. The track can provide a maximum horizontal force of 3.50 N resulting in circular motion. What is the minimum time that the train can take to travel once around the track. Assume the that the train maintains a constant speed. State the time in seconds to 2 decimal places. Do NOT include units in your answer.
q2. A 2.0 kg mass attached to a 1.5 m string is being spun in a vertical circle at a constant speed of 5.0 m/s. What is the tension in the string when the mass is at the top of the circle?
