Suppose a 1800-kg car passes over a bump in a roadway that follows the arc of a circle of radius 18.4 m as in the figure shown below.

Question

(a) What force does the road exert on the car as the car passes the highest point of the bump if the car travels at 9.24 m/s? (Neglect any friction that may occur.)
magnitude
im getting 8352.a56N but it is incorrect i did 1800*9.24^2/18.4 and i got 835

Incorrect: Your answer is incorrect.
N
direction
Correct: Your answer is correct.

(b) What is the maximum speed the car can have without losing contact with the road as it passes this highest point?

13.44

Correct: Your answer is correct.
m/s

Answer 1

v^2/R = 9.24^2/18.4
= 4.64 m/s^2 centripetal acceleration
so
apparent weight on road
= m (g-4.64)
= 1800 (9.81 - 4.64)
= 9306 N
