(II) A car moving in a straight line starts at x = 0 at t
Chapter 2, Problem 21P(choose chapter or problem)
A car moving in a straight line starts at x = 0 at t = 0. It passes the point x =25.0 m with a speed of 11.0 m/s At t = 3.00s. It passes the point x =385 m with a speed of 45.0 m/s, t = 20.0 s
Find (a) the average velocity, and (b) the average acceleration, between t = 3.00 s and t =20.0 s.

QUESTION:
A car moving in a straight line starts at x = 0 at t = 0. It passes the point x =25.0 m with a speed of 11.0 m/s At t = 3.00s. It passes the point x =385 m with a speed of 45.0 m/s, t = 20.0 s
Find (a) the average velocity, and (b) the average acceleration, between t = 3.00 s and t =20.0 s.
ANSWER:
Step 1 of 2
Initial position
Position at t=3s:
Position at t=20s:
Velocity at t=3s
Velocity at t=20s:
Distance travelled between t=3s, and t=20s:
