Q1. An airplane is flying in a horizontal circle at a speed of 88.50 m/s. The 39.50 kg pilot does not want his radial acceleration to exceed 2.90 g.

The acceleration of gravity is 9.80 m/s2.

What is the minimum radius of the circular path?

Q2. An 1150-kg car pulls a 450-kg trailer. The car exerts a horizontal force of 3,800 N against the ground in order to accelerate. What force does the car exert on the trailer? Assume an effective friction coefficient of 0.15 for the trailer.
