Question

A bird, accelerating from rest at a constant rate,

experiencesa displacement of 28 m in 11 s. What is the final
velocity after 11s?

Answer 1

the speed of the bird is 2.8 m/s in after 11 seconds.

Step-by-step explanation:

given,

displacement of bird = 28 m

time taken of the displacement of 28 m = 11 s

distance = speed × time

velocity =
`(displacement)/(time)`

=
`(28)/(10)`

= 2.8 m/s

hence, the speed of the bird is 2.8 m/s in after 11 seconds.
