Abus and a small car accelerate from a set of traffic lights to a speed of 18m/s. although they are both travelling at the same speed, the change in momentum for the bus is much greater than the change in momentum of the car.
explain why.

Which of the following describe possible scenarios? a) an object has zero instantaneous velocity and non-zero acceleration. b) an object has negative acceleration and is speeding up. c) an object has positive acceleration and constant velocity. d) an object has positive velocity and zero acceleration. e) an object has increasing positive position and negative velocity. f) an object has decreasing positive position and negative acceleration.
