Maximum speeds for curves depend on the weather conditions due to their effect on the coefficient of friction.  Determine the minimum coefficient of static friction needed for a car to travel around 75.0 m radius, flat, circular curve at 25.0 m/s without skidding.

A satellite of mass 400 kg, orbiting the Earth, travels in a circular orbit of radius 7500 km at a constant speed of 7300 m/s.  What is the acceleration of the satellite?

An object traveling at 3.0 m/s accelerates at 4.0 m/s2 when a force of 14.0 N is applied. What is the mass of the object?
