QUESTION:
A test car travels in a straight line along the x- axis. The graph in Fig. E2.11 shows the car’s position x as a function of time. Find its instantaneous velocity at points A through G.
ANSWER:
Step 1 of 4
We can calculate the instantaneous velocity at any point as the slope of the tangent line to the graph at that point.
Portion of the curve on which A and B lies appears to be approximately a line segment.
So, we can find the slope of the line, which gives the instantaneous velocity at the point.
