Question

A car travels at a speed of 19 m/s around a
curve of radius 35 m. The acceleration of gravity is 9.8 m/s^2 .
a: What is the net centripetal force needed to
keep the car from skidding sideways?
Answer in units of N
b:Were there no friction between the car’s tires
and the road, what centripetal force could be
provided just by the banking of the road?
Answer in units of N
c:Now suppose the friction force is sufficient to
keep the car from skidding. Calculate the
magnitude of the normal force exerted on the
car by the road’s surface. Hint: Check the
correctness of your answer to the first question

Answer 1

d:Calculate the magnitude of the friction force.
Answer in units of N
e:Calculate the lowest possible value of the
static friction coefficient μs that would pre-
vent the car from skidding.
