A race car starts from rest in the pit area and accelerates at a uniform rate to a speed of 35 m/s in 11s, moving on a circular track of radius 500 m.
Determine the tangential and centripetal components of the net force excreted on the car(by the ground) when it's speed is 15 m/s. the cars mass is 1100 kg.

Tangential force = (tangential acceleration) x (mass)
= (35/11)m/s^2*1100 = 3500 N
Centripetal force at 15 m/s = (V^2/R)*(mass)
= 15^2/500 x 1100 = 495 N
(It continues to rise as the car accelerates)
