At t = 0, two cars are traveling at the shown positions and speeds. Car A has a constant acceleration of a^, and car B has a constant deceleration of a B. At t = 12.55 sec, car A overtakes car B at 534 ft. Determine the values of aA, and aB. at 108 = 40 sec V = 30c B 150'

At the instant shown, cars A and B are travelling at the speeds shown. If B is accelerating at 1200 mi/h2 while A maintains a constant speed, determine the magnitude of the velocity and acceleration of B with respect to A. Car B moves along the curve having a radius of curvature of 0.7mi.  show all the steps in the solution please

Plz expert solve correctly

An accelerometer C is mounted to the side of the roller-coaster car and records a total acceleration of 3.0g as the empty car passes the bottommost position of the track as shown. If the speed of the car at this position is 205 km/h and is decreasing at the rate of 18 km/h every second, determine the radius of curvature p of the track at the position shown. Answer: p= i m 0.76 m
