Question: A State Trooper vehicle is pacing cars. At that instant shown, the patrol car has a speed vA =18 m/s and is slowing down at a rate of 2 m/s2 . Your car has a speed of vB = 12 m/s while the tangential component of acceleration of your car is 3 m/s2 . Find the magnitude of acceleration of your car relative to the patrol vehicle. The angle of the freeway with respect to the horizontal is ? = 60° degrees and the radius of the ramp is r = 100 m.
