Uniform Circular Motion Problem solving Receipe 1. Draw a free-body diagram. 2. Identify the unbalanced force, towards the center of the circle. 3. Set the unbalanced force equal to centripetal force.
Car on a Flat-Curve Problem: At what maximum speed can a car safely negotiate a horizontal unbanked turn (radius = 51 m) in dry weather (coefficient of static friction = 0.95)?
Banked Curves 26. What is the ideal speed to take a 100 m radius curve banked at a 20.0 angle?

Acceleration Due to Gravity Calculate the surface gravity for a planet Earth. Gravitational constant = G = 6.673 x 10-11N.m2/kg2. Mass of Earth = 5.98 x 1024kg. Mean Radius of Earth = 6380 km.
Satellites in Circular Orbits Determine the speed of the ISS, orbiting the Earth, at an altitude of 390 km above ground. Gravitational constant = G = 6.673 x 10-11N.m2/kg2. Mass of Earth = 5.98 x 1024kg. Mean Radius of Earth = 6380 km.
