Question

A high-performance automobile can accelerate approximately as shown in the figure below in the velocity-time graph. (The short flat spots in the curve represent shifting of the gears.)

Estimate how far the car traveled while in third gear.

Answer 1

use the equation v = d / t

re arrange for d = v x t

take inputs v and t for the third gear values in the graph

Answer 2

So basically find the area under the third gear curve, right? I got about 150m, but the computer says that's wrong

Answer 3

is the answer close to 85?

Answer 4

no
