(b) The automobile in Figure 1b is originally at rest when (arclength) s = 0. If its speed then increases according to j = (0.062) ms ?, where t is in seconds, determine the magnitudes of its velocity and acceleration at s = 120 m. Hint: The automobile will be on the curved path so use normal and tangential components. (14 marks) 90 m 75 m Figure 1b
