Question

A bird starts from rest and accelerates at 2.0 m/s^2 forward for 5.0 s. What is the displacement of the bird during this time?

Answer 1

The bird's displacement, when accelerating at 2.0 m/s^2 for 5.0 s from rest, is 25 meters.

Step-by-step explanation:

The displacement of an object under constant acceleration can be calculated using the equation s = ut + (1/2)at^2, where s is the displacement, u is the initial velocity, a is the acceleration, and t is the time. In this case, a bird starts from rest (u=0) and accelerates at 2.0 m/s^2 for 5.0 s. We plug these values into the equation to find the displacement:

s = (0*5.0 s) + (1/2)(2.0 m/s^2)(5.0 s)^2

s = 0 + (1/2)(2.0 m/s^2)(25 s^2)

s = (1.0 m/s^2)(25 s^2)

s = 25 m

The bird's displacement is 25 meters.
