Lab- Observation of Motion

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

s(m)	0	0.25	0.50	0.75	1.00	1.25	1.50
t(s)	0.00	0.45	0.71	0.77	0.98	1.07	1.12
t2
a

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.
