Question

The car travels around the portion of a circular track having a radius of r = 400 ft such that when it is at point A, it has a velocity of 3 ft/s, which is increasing at the rate of 1.003t ft/s^2, where t is in seconds (Figure 1). Part A: Determine the magnitude of the velocity when it has traveled three-fourths of the way around the track. Express your answer to three significant figures and include the appropriate units. Value: Units: Part B: Determine the magnitude of the acceleration when it has traveled three-fourths of the way around the track. Express your answer to three significant figures and include the appropriate units. Value: Units:
