A remote controlled toy car starts from rest and begins to accelerate in a straight line. The figure below represents "snapshots" of the car's position at equal 0.5 s time intervals. (Assume the positive direction is to the right. Indicate the direction with the sign of your answer.) 1=0s t=0.5s 1=1.0s 0m 0.1 m 0.4 m 1=1.5 s 0.9 m t=2.0 s (a) What is the car's average velocity (in m/s) in the interval between t = 0.5 s tot 1.0 s? 0.6 m/s 1.6 m (b) Using data from t = 0.5 s to t = 1.5 s, what is the car's acceleration (in m/s) at t = 1.0 s? 0.4
