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

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

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

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

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 . . .

3) A particle is moving along a straight line with velocity v(t) = t2 – 7t +10 ft/sec. Find the displacement and distance on the interval [1, 7]

3) A particle is moving along a straight line with velocity v(t) = t2 – 7t +10 ft/sec. Find the displacement and distance on the interval [1, 7]
