Question

A curve in a road forms part of a horizontal circle. As a car goes around it at constant speed (12 m/s), the total force on the driver has a magnitude of 146 N. What is the total vector force (in N) on the driver if the speed is 18 m/s instead?

    Answer:

    a1 =  v1^2 / R

    a2 =  v2^2 / R

    a2 = (v2 / v1)^2 = (3 / 2)^2 = 9/4

    F2 = 9/4 * F1 = 9/4 * 146 = N     329 N      since F = m * a
