Question

   A is moving at 25 m/s when the driversteps on the brakes and brings the bus to astob in 3.0 s.           a . What is the averageacceleration of the bus while braking ?             b . If the bus tooktiwice as long to stop , how would the acceleration compare withwath you            found in the part a ?    A is moving at 25 m/s when the driversteps on the brakes and brings the bus to astob in 3.0 s.           a .

Explanation / Answer

Here initial velocity(u) = 25 m/s Final velocity = 0 m/s Also time (t) = 3.0 sec Using the equation , v =u+at Putting the values , 0 = 25 + a*3 =>a =8.33 m/s2 b )if time becomes 6 sec , Using the same equation , a =25 / 6 = 4.17 m/s2
