**1. Homework Statement**

At the beginning of a 10 sec. interval your position is measured to be 80 ft East with respect to a reference object. At the end of the 10 sec. interval your position is measured to be 965 ft East with respect to the same reference object.

Determine your velocity at t = 3.45 sec.

Determine your velocity at t = 6.9 sec.

Calculate the area under the entire V-t graph. What does this area respresent?

**2. Homework Equations**

m(slope) = v = change in x divided by change in t = Xf - Xo/tf - to =

965ft - 80ft/10 sec- 0sec = 885ft/10sec = 88.5met/sec. East

**3. The Attempt at a Solution**

Area = Vot = 10 sec times 88.5 met/sec = 885 meters This represents the displacement of the car.

The velocity of the car at t = 3.45 sec and at t = 6.9 sec is 88.5 met/sec.
