Question 1 - A cart on a linear track has a uniform acceleration of 0.172m/s2. What is the velocity of the cart 4.00 s after it is released from rest?
• How far does this cart travel during these 4 s?
• From the first equation, give the expression of the acceleleration a.
In table 1 is a data set of time and distance traveled.
Question 2 -
• Complete table 1
• Find the average acceleration
Table 1: Average values of time are below the corresponding values of distance

Question 3 - use the collected data in table 1 and:
• Plot distance versus time
• is this a uniform motion? Explain
Question 4 - Use the collected data in table 1 and:
• Plot 2Δs versus t2
• Give an interpretation of the slope of this graph
• Extract the average acceleration from the graph, and compare with the previously calculated one.

What is the image distance
: The actual person (not his or her image) is the object, and the object (person) is behind (outside) the van. The object distance is positive (since it is a real object), and light is traveling from the object (the person), through the lens, and to..
