Question

A bird accelerating from rest at a constant rate , experiences a displacement of 28m in 11s .what is the final velocity after 11s?

Answer 1

308m/s

Step-by-step explanation:

Let the final velocity, displacent, time taken and initial velocity be V, S, T and U respectively.

Given,

U=0( The bird started from rest)

T= 11s

S=28m

then,

V=U+S×T

or, V=0+11×28

or, V= 308m/s
