A bird flies for 4s with a velocity `V=(t-2) m//s` in a straight line where t= time in second Calculate the displacement and distance covered by the bird

A

`4m`

B

`6m`

C

`8m`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
A
Plotting velocity `v` against time `t,` we get

Area under time `v-t` curve gives distanct.
Distance `=(1)/(2)xx2+(1)/(2)xx2xx=4m`

A body moving along a straight line traversed one third of the total distance with a velocity 4 m//sec in the first stretch. In the second stretch, the remaining distance is covered with a velocity 2 m//sec for some time t_(0) and with 4 m//s for the remaining time. If the average velocity is 3 m//sec , find the time for which body moves with velocity 4 m//sec in second stretch:
