Question

A 905 kg test car travels around a circular track with a circumference of 3.25 km. If the magnitude of the force that maintains the car's circular motion is 2140 N, what is the car's tangential speed?

Answer 1

from circumference, find radius.

force= mass*v^2/r

solve for v.

Answer 2

29kg

Answer 3

35 m/s
