A bus moves along an x-axis a distance of 800 m, starting at rest (at x = 0) and ending at rest (at x = 800 m). Through the first 2 of that distance, its acceleration is +2.15 m/s?. Through the rest of the distance, its acceleration is -0.92 m/s?. Calculate a) time taken to cover the first half of the distance? b) the bus's maximum speed? c) total time to cover 800 m distance? Sketch velocity time graphs.
Is it possible for an object to have zero velocity and constant nonzero acceleration?
O Yes, but only if it is not moving at all.
O No, if its velocity is zero its acceleration must also be zero.
Yes, all objects with zero velocity have nonzero acceleration.
Yes, but its velocity must only be zero for an instant.
O No, if its acceleration is not zero its velocity cannot be zero.
