The car is traveling at a constant speed v0 = 80 km/hr on the level portion of the road. when the 4-percent (tan q = 4/100) incline is encountered, the driver does not change the throttle setting and consequently the car decelerates at the constant rate g sin q. determine the speed of the car: (a) 28 seconds after passing point a ,and (b) when s = 620 m.
