1
Straight Line Motion Looking at position, velocity, and acceleration from the integral.

2
What does s(t), v(t), and a(t) mean? How are they connected?

3
1) a(t) = 4t – 6 and the initial velocity is 3, find v(t).

4
2) a(t) = sin t + 2t and the initial velocity is 5, find v(t).

5
Displacement and Distance 80 miles to the right then turn around … Go 30 miles back Displacement = 80 – 30 or 50 miles Distance = or 110 miles Can displacement equal distance? How?

6
Displacement and Distance 80 miles to the right then turn around … Go 30 miles back Given a particle moving on a straight line with velocity v(t) between time t = a and time t = b then...
