A graph of position versus time for a certain particle moving

along the x - axis is shown in Figure P2.6. Find the instantaneous

velocity at the instants (a) t = 1.00 s, (b) t = 3.00 s,

(c) t = 4.50 s, and (d) t = 7.50 s.

Step 1

Instantaneous velocity of a particle is equivalent to the slope of the distance time graph. The expression for the Instantaneous velocity is:

Step 2

(a)

Take the points at* t *= 0 s and *t *= 1 s, the plot is straight line. So, these two points can be taken in order to find the slop of the graph that is the instantaneous velocity at time *t *= 1 s.

Step 3

(b)

Take the points at* t *= 2 s and *t *= 3 s, the plot is straight line. So, these two points can be taken in order...
