Question
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.)
t = 0s t=0.5 s t= 1.0 s
t = 1.5 s
t= 2.0 s
0m 0.1 m
0.4 m
0.9 m
1.6 m
(a) What is the car's average velocity in the interval between t = 1.0 s to t = 1.5 s?
m/s
(b) Using data from t = 1.0 s to t = 2.0 s, what is the car's acceleration at t = 1.5 s?
m/s?
(c) Is the car's speed increasing or decreasing with time?
increasing
