A toy car, mass of 0.025 kg, is traveling on a horizontal track with a velocity of 5 m/s. If the track then starts to climb upwards, how high up the track can the car reach?

Acar of mass m goes around a banked curve of radius r with speed v. if the road is frictionless due to ice, the car can still negotiate the curve if the horizontal component of the normal force on the car from the road is equal in magnitude to 101) a) mv2/r b) mg/2. d) mg e) tan[v2/(eg)]
