If we apply the above equations to the case of an object that does not change its direction of travel as it moves with constant acceleration, we find that the object: Undergoes a displacement Ax = x- x, . Note that displacement is a positive quantity if x > x, and a negative quantity if x < x,. Has average velocity v = (x - x )/t = (v + vo)/2. Note that velocity has the same sign as displacement. Travels distance d = |Ax| = |x – x,| . Note that distance is always a positive quantity. Has average speed d/t . Note that speed is always a positive quantity. Has constant acceleration a = (v – vo)/t . Acceleration may be positive or negative, depending on how velocity changes. - Xo For the case of an object that does change its direction of travel as it moves with constant acceleration, which of the quantities listed above are different?

Traffic shock wave. An abrupt slowdown in concentrated traffic can travel as a pulse, termed a shock wave, along the line of cars, either downstream (in the traffic direction) or upstream, or it can be stationary. The figure shows a uniformly spaced line of cars moving at speed v = 27.0 m/s toward a uniformly spaced line of slow cars moving at speed vs = 5.30 m/s. Assume that each faster car adds length L = 13.0 m (car length plus buffer zone) to the line of slow cars when it joins the line, and assume it slows abruptly at the last instant. (a) For what separation distance d between the faster cars does the shock wave remain stationary? If the separation is twice that amount, what are the (b) speed and (c) direction (upstream or downstream) of the shock wave?
Question 6 of 20 Suppose you are driving due east, traveling a distance of 1500 m in 2 minutes. You then turn due north and travel the same distance in the same time. What can be said about the average speeds and the average velocities for the two segments of the trip? O The average speeds and the average velocities are the same. O The average speeds are the same, but the average velocities are different. O The average speeds are different, but the average velocities are the same. 6
You travel from point A to point B in a car moving at a constant speed of 70 km/h. Then you travel the same distance from point B to another point C, moving at a constant speed of 90 km/h. Is your average speed for the entire trip from A to C 80 km/h? Explain why or why not.

You are driving your car uphill along a straight road. Of Suddenly, you see a car go through a red light and enter the intersection, just ahead of you. you. You immediately apply your brakes and skid straight to a stop, leaving a 100 ft long mark from the landslide. A policeman observes the whole incident, give the driver of the car a ticket for running a red light. He also gives a ticket to you for exceeding the 30 mph speed limit. When you get home, you read your physics book and you may notice that the coefficient of kinetic friction between the tires and the road was 0.60, and the coefficient of static friction was 0.80. You estimate that the hill makes an angle of about 10° with the horizontal. Check the manual owner and find that your car weighs 2,050 lbs. Are you going to claim the traffic ticket? in the court? Support your argument. Please type answer not write by hend
Complete solution and answer must be simplified. A particle is moving on a straight line has acceleration a=5-3t and it's velocity is 8 at time=2. If s(t) is the distance from the origin, find s(2) -s(1). Note : s (t) = f v dt v (t) = f a dt
