For unlimited access to Homework Help, a Homework+ subscription is required.
1- Define velocity and acceleration in terms of position and time.differentiate between the instantaneous quantities and the averagequantities.2- how are average velocity and instantaneous velocity related foran object moving at constant and non constant velocity?3-how would you expect the graph of position versus time to lookfor a car moving at constant and non constant velocity on a track?explain how the graph would be?4- what would a graph of instantaneous velocity versus time looklike for a car moving with constant velocity? or a car speeding up?or if the car is slowing down?your help is much appreciated.

(a) Its velocity is constant, but its acceleration is changing.
(b) Its acceleration is constant, but its velocity is changing.
(c) Both its velocity and acceleration are changing.
(d) Its velocity and acceleration remain constant.
