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?
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
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.
