Figure given here shows the variation of velocity of a particle with time. Find the following: (i) Displacement during the time intervals. (a) 0 to 2 sec., (b) 2 to 4 sec. and (c) 4 to 7 sec (ii) Accelerations at (a)t = 1 sec, (b) t = 3 sec. and (c)t = 6 sec. (iii) Average acceleration (a) between t = 0 to t = 4 sec. (b) between t = 0 to t = 7 sec. (iv) Average velocity during the motion. |

Answer» Solution :(i)DISPLACEMENT =Area enclosed between v-t GRAPH and time axis. (ii) Acceleration = slope of v-t curve (iii) AVERAGE acceleration=`"TOTAL change in velocity"/"Total time"` (iv) Average velocity =`"Total displacement "/"Total time "` |
