A bird flies for `4 s` with a velocity `v=(t-2) ms^(-1)` in a straight line. Calculate the displacement of the bird ans distance traveled by the bird.

Text Solution

Verified by Experts

On plotting a grapg between velocity (v) and tiem (t) we get a curve asd shown in Fig. 2 ( CF). 75. The distance coverd in ` 4` seconds is the area under the crev ABC with tiem axis. So distance trvelled is
` S=area of Dleta OAB +area of Delta BCD`
` =(2 xx 2 )/2 + (2 xx 2)/2 4 m`
