Question

A toy car moves along the x axis, and its velocity as a function of time is plotted below. Take the positive x direction to be forwards. The curved part of the graph from t = 2 s to t = 4 s forms a semicircle. 

PLEASE look at the picture to answer all of the parts to this question. 

Part 1) In words, please describe the motion of the car. Make specific reference to different intervals of time, whether the car is moving forwards, backwards, or is stationary, and whether it is speeding up, slowing down, or moving at a constant speed. 

Part 2) What is the instantaneous acceleration of the car from t = 0 s to t = 2 s ? 

Part 3) What is the average acceleration of the car from t = 2 s to t = 4 s ? 

Part 4) At t = 8 s, what is the displacement of the car from its original position? 

Part 5) What is the instantaneous velocity of the car at t = 3 s ? 

Please answer all of the parts of this question clearly.
