In anticipation of a long 7° upgrade, a bus driver accelerates at a constant rate of 3 ft/s2 while still on a level section of the highway. Knowing that the speed of the bus is 60 mi/h as it begins to climb the grade and that the driver does not change the setting of his throttle or shift gears, determine the distance traveled by the bus up the grade when its speed has decreased to 50 mi/h.

A car is driven over a measured mile in 1.5 min. Determine the speedof the car (a) in miles per hour and (b) in feet per second.

Q22. As shown in the image below, a motorcycle travels along circular path from point A to point B. Its decreases at at = − (C. s) m/s², where Cis a constant and s is the distance (in m) traveled along the path measured from point A. If the constant C is 0.002, and the motorcycle has speed of 32 m/s at point A, determine the magnitude of its total acceleration (in m/s2) at point B. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. .A Your Answer: Answer A 300 m n 90° B
