Linear Motion WS #4 (page 2)
6. The graph below represents the relationship between distance and time for an object. What is
the instantaneous speed of the object at t = 5.0 seconds
7. The diagram below shows a worker moving a 50.0 kilogram safe up a ramp by applying a
constant force of 300. Newtons parallel to the ramp. The data table shows the position of the
safe as a function of time.
a. Using the information in the data
table, construct a line graph. Plot
the data points and draw the
best-fit line.
b. Calculate the slope of the best fit
line. Show ALL work using the
GUESS method.
c. Using one or more complete sentences, explain the physical significance of the slope
of the graph.
