Fig. shows the graph of the x-coordinate of a particle going along the x-axis as a function of time. Find (a) the average velocity during `0` to `10 s,` (b) instantaneous velocity at 2, 5, 8 and 12s.

Text Solution

Verified by Experts

The correct Answer is:
A, B
(a) Average velocity=`s/t=(x_f-x_i)/t`
`=(x_(10 sec)-x_(0 sec))/10=100/10=10m//s`
(b) Instantaneous velocity =Slope of x-t graph
