 Question

2/29 The car is traveling at a constant speed vo km/h on the level portion of the road. When the 6-percent (tan 0 6/100) incline is encountered, the driver does not change the throttle setting and con- sequently the car decelerates at the constant rate g sin 0. Determine the speed of the car (a) 10 seconds after passing point A and (b) when s 100 m. = 100 Ans. (a) u = 21.9 m/s, (b) u = 25.6 m/s A Problem 2/29
