- A motorist starts from rest at point A on a circular entrance ramp when t=0, increases the speed of her automobile at a constant rate and enters the highway at point B. Knowing that her speed continues to increase at the same rate until it reaches 62.5 mph at point C, determine themagnitude of the normal acceleration (ft/s2) at t=10s.arrow_forwardCars A and B are traveling in adjacent highway lanes and at t = 0s have the position and velocity shown. If va = 12.5 km/h , va = 25.4 km/h , S = 615 m, and knowing that car A has a constant acceleration of 0.69 m/s and that B has a constant deceleration of 0.27 m/s?, determine the relative velocity of car B with respect to car A at the moment car A overtake car B.

The camera is mounted on a mechanism which permits it to record the motion of the car as the car travels on straightaway BC. It took 0.5 s for the car to travel from the position e = 60° to the position e = 35°. Knowing that b= 26 m, determine the average speed of the car during the 0.5-s interval.
