A car with mass 729 kg passes over a bump in a road that follows the arc of a circle of radius 34.6 m as shown in the figure. The acceleration of gravity is 9.8 m/s^2. What is the maximum speed the car can

have as it passes the highest point of the bump before losing contact with the road?
Answer in units of m/s

Thank you for the opportunity to help you with your question!

g = v^2/r

9.8 = v^2/34,6
v^2 = 9.8*34.6
v = sqrt ( 9.8*34.6 ) = 18.41 m/s

Please appreciate my help and select my answer as the best! Thanks :)
