3,70
4,119
5,178

Find the average velocity for the time period beginning when t=2 and lasting
(1) 3 seconds, (2) 2 seconds, (3) 1 second

Answer 1

(1) Average velocity = (70 - 32) / 3 = 18 m/s
(2) Average velocity = (70 - 32) / 2 = 19 m/s
(3) Average velocity = (70 - 32) / 1 = 38 m/s

Answer 2

I have no idea what the bot is doing.

a) start at t = 2 for 3 seconds:
avg v = (178-32)/3 = about 48.7 m/s
b) start at t = 2 for 2 seconds
avg v = (119-32) / 2 = ....
etc
