1. your car is approaching a curve of radius 40 meters. te manufacturer of your car's tires says that the can create a centripetal force (through friction) of 12, 100 N with the ground
A) if you car has a mass of 1000 kg how fast can you take the corner without skidding
B) on an icy day the friction of your tires can only exert a centripetal force of 900N, how fast can you take the same corner ?
2) the moon has a mass of 7.3 x 10^22 kg and orbits the earth at an average radius of 3.8 x 10^8 meters. it completes one orbit around the earth in about 27.3 days
what is the moon's linear velocity? what is the moon's centripetal acceleration?
3. a body of mass 0.1 kg is been rotated in a circular path of diameter 1 m on a frictionless horizontal plane bye means of a string. it performs 10 revolutions in 31.4 sec. calculate the centripetal force acting on the body.
