A car drives over the top of a hill that has a radius of 30 m. Maximum speed can the car have without flying off the road at the top of the hill is 17.14 m/s

The given parameters;

radius of the hill, r = 30 m

The centripetal force must be equal to or greater than the car's weight to determine the maximum speed of the vehicle on a hill.

F=mg

mv²/r = mg

v=√rg

v=√30*9.8

v=17.14 m/s

In contrast to velocity, which describes the speed and direction of an object's movement, speed is the rate of movement along a path. Alternatively, velocity is a vector and speed is a scalar quantity. No speed can be negative or zero. velocity can be zero or negative. What moves quickly is referred to as speed. With a direction comes velocity.
