What is the magnitude of the total acceleration of the car when its speed is 30 m/s? (A) 5.00 m/s 2 (B) 5.46 m/s 2 (C) 6.04 m/s 2 (D) 6.73 m/s 2 Problem 2: The airplane is tracked by radar, which records r, , and at regular intervals. The readings at a certain instant are r =1000 m, = 38.4, = 0.0367 rad/s, and = 0 If the airplane is in level flight at an elevation of h, calculate its speed and acceleration at this instant.
