Concept #1: Calculating Average and Instantaneous Velocity from the Position Function

Practice: The position function for a particle moving on the x-axis is x(t) = −2t2 + 18t + 7. What is the particle’s initial velocity?
A) v0 = 18 m/s
B) v0 = 7 m/s
C) v0 = 9 m/s
D) v0 = 4.5 m/s

Example #1: Stopping Position

Practice: The position of a small object is given by x = 0.6e2t – 1, where t is in seconds and x in meters. At what time is the small object travelling with a velocity v = 65.5m/s?

A) 2.35 s
B) 2.0 s
C) 2.69 s
D) Never

Concept #2: Calculating Position and Displacement from Velocity Functions

Practice: A ball’s velocity is given by v(t) = 1/2 t3 − 2t. Calculate the ball’s displacement from t = 1.5s to t = 3s.

A) 8.81 m
B) 2.74 m
C) 35.0m
D) –2.74 m
