Arrange the balls in order from greatest amount of gravitational potential energy to least.

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)]

How are calculation for velocity and speed different

Zeros that follow non-zeros numbers and are also to the right of a decimal point are significant
