A curve of radius 20 m is banked so that a
970 kg car traveling at 50 km/h can round it
even if the road is so icy that the coefficient of
static friction is approximately zero.
The acceleration of gravity is 9.81 m/s^2
Find the minimum speed at which a car can
travel around this curve without skidding if
the coefficient of static friction between the
road and the tires is 0.3.
Answer in units of m/s

Find the maximum speed under the same
conditions.
Answer in units of m/s

Thanks in advance :)
