Question

I am really confused on the steps to solve this problem. This is my first time taking physics. The much needed help, would be strongly appreciated.

a) Calculate the centripetal force exerted on a vehicle of mass m = 1630 kg that is moving at a speed of 13.9 m/s around a curve of radius R = 385 m.

b) Which force plays the role of the centripetal force in this case?
a- force of static friction
b- spring force
c- gravitational force
d- normal force
e- tension force

Answer 1

m v^2/r
= 1630 * (13.9)^2/385

b)
I do not know what is holding your vehicle in the circle !!!!
If on a string - tension force
If held in a big cylinderical rotating can (carnival ride) - normal force
If on a flat curving road - friction on the tires
If in orbit in space - gravitational force
If on a spring - spring force
If on a banked road banked correctly for this speed - normal force

Answer 2

Thank you so much.
