IN CLASS PRACTICE PROBLEMS

ANSWER KEY

NOTES This handout is on my Connect site under “Physics – Handouts.” It’s called “Acceleration from a d-t graph”

1.Graph the data on a d-t graph 2.Smoothly sketch a best-fit curve 3.Find 4 points on the curve (evenly spaced apart) and calculate the instantaneous velocity (show tangent line and all work) 4.Fill in this table 5.Sketch a v inst -t graph 6.Calculate the slope (with units!) 7.Fill in the blank: The slope tells us the ________ of the plane. Group Work – Acceleration from a d-t graph Displacement (m) Time (s) v inst (m/s) Instant in time (s) Table 1: Displacement of a plane taking off

ANSWER KEY

v inst (m/s) Instant in time (s)

ANSWER KEY The slope tells us the acceleration of the plane.
