A car of mass 1,000kg moves in a circular path of radius of 50 meters. .The constants speed of the car is given by 12m/2.
A) What is the centripital force of the car?
B) If the car rounds the curve in problem A and moves in a ne circular path of radius 48.2 meters with a centripital accleration of 8.05m/s^2, whst is the tangential speed of the car?
