A tram starts from rest atone station and comes to a stop one minute later at the next. It accelerates uniformly at 2m/s2 until it reaches a speed of 20m/s. It travels at this constant speed for a certain time until it decelerates back to rest at 4m/s2. Find the average velocity of the tram over the entire journey.

  • applied maths -

    The average velocity=distance/time, time=60s
    distance=2*10^2/2+20*45+4*5^2/2=1050m
