A 259 g cart moves down a track that is inclined. There is friction You are given the data
for the cart in the table below.
t (s)
y (cm)
v (m/s)
0.541
16.1
0.655
2
0.785
13.3
0.936
3
0.971
11.0
1.112
4
1.091
8.9
1.259
For each event, find K, Ug, and E and record these in your data table. Have EXCEL
make a graph of K, Ug, and E (vertical axis) and (horizontal axis). For the chart type,
select Scatter with Smooth Lines and Markers. All three should be on one graph. To
do this, first create the K and t graph, then repeat this process for Ug and E, always
selecting i for the x-axis.
Find AK, AUg, and AE. Use I and 4 as the initial and final events. Record these in your
EXCEL file.
The loss of energy is equal to the work done by friction. How much work is done by
friction between events I and 4?
