An emu moving with constant acceleration covers the distance between two points that are 92 m
apart in 6.5s. its speed as it passes the second point is 14 m/s.

a)

b)

Explanation:

The complete question is written below:

An emu moving with constant acceleration covers the distance between two points that are 92 m  apart in 6.5s. Its speed as it passes the second point is 14 m/s. What are (a) its speed at the first point and (b) its acceleration?

Since we are talking about constant acceleration, we can use the following equations:

(1)

(2)

Where:

is the distance between the two points

is the velocity of the emu at the first point

is the velocity of the emu at the second point

is the time it takes to the emu to cover the distance

is the emu's constant acceleration

Knowing this, let's begin with the answers:

In this situation wi will use equation (1):

(1)

Finding :

(3)

(4)

(5)

Now we will substitute (5) in equation (2):

(6)

Finding :

(7) This means the emu is decreasing its speed at a constant rate.
