Question
A 600-kg car traveling at 30.0 m/s is going around a curve having a radius of 120 m that is banked at an angle of 25.0'. The coefficient of static friction between the car's tires and the road is 0.300. What is the magnitude of the force exerted by friction on the car?

A car is parked on a cliff overlooking the ocean on an incline that makes an angle of 15.0° below the horizontal. The negligent driver leaves the car in neutral, and the emergency brakes are defective.
For this problem, include the negative sign for virtual images. An object is located 30cm from a lens with a focal length of 10cm. If the lens is concave (diverging), how far from the lens is the image
A railroad freight car weighing 289 kN and traveling at 1.52 m/s overtakes one weighing 207 kN and traveling at 0.910 m/s in the same direction. Find the loss of kinetic energy during collision
Eventually the magnetic force on the bar due to the induced current exactly balances the weight (Mg) of the bar, and the acceleration of the bar becomes zero. After that point, the bar continues to fall with a constant, terminal, velocity. Determi..
