Q1. A train 350 m long is moving on a straight track with a speed of 84.4 km/h. The engineer applies the brakes at a crossing, and later the train's last car passes the crossing with a speed of 16.3 km/h. assuming constant acceleration, determine how long the train blocked the crossing. Disregard the width of the crossing.

Q2. A car of mass = 1400 travelling at 60.0 enters a banked turn covered with ice. The road is banked at an angle, and there is no friction between the road and the car's tires. Use = 9.80 throughout this problem.

What is the radius of turn if theta = 20.0 (assuming the car continues in uniform circular motion around the turn)?
