Answer:
(a) . distance traveled during first 2 second
= area of triangle till 2 seconds.
= 1/2 * 2 *15
= 15m.
(b) clearly visible that object has a constant velocity from 2 second to 5 second. because velocity vs time graph is straight line with slope equal to 0 during this interval of time.
(c) distance traveled during retardation is area of graph from time t= 5 to t= 6 seconds.
- it is triangle, so we use area of triangle formula.
- so distance= 1/2* 15*(6-5)
= 15/2
= 7.5 m
