Situation 3. A road having a radius of 120m and has angle of 9.31 degrees from the horizontal. The center of gravity of the car is located 0.80m above the roadway and the distance between the two front wheels is 1.20m. If the car has a total weight of 15 KN, a. Compute the normal acceleration and the velocity of the car before overturning. b. If uk= 0.60, what is the velocity of the car without sliding? Please answer this with a complete solution and with a Free Body Diagram PLEASE. Thank you.
Car A starts from rest at t = 0 and travels along a straight road with a constant acceleration of 6 ft/s^2 until it reaches a speed of 80 ft/s. Afterwards it maintains this speed. Also, when t = 0, car B located 6000 ft down the road is traveling towards A at a constant speed of 60 ft/s. Determine the distance traveled by car A when they pass each other.
Two automobiles A and B are approaching each other in adjacent highway lanes. At t=0, A and B are 1km apart, their speeds are 108km/h and 63km/h and they are at the points P and Q respectively. Knowing that A passes point Q 40s after B was there and B passes P 42s after A was there, determine the uniform acceleration of A and B, when the vehicles pass each other and the speed of B at that time.
