Question

A bald eagle is flying to the left with a speed of 34
meters per second when a gust of wind blows back
against the eagle causing it to slow down with a
constant acceleration of a magnitude 8 meters per second
squared. What will the speed of the bald eagle after
the wind has blown for 3 seconds ?​

Answer 1

Given : bald eagle is flying to the left with a speed of 34 m/s . a gust of wind blows back  against the eagle causing it to slow down with a  constant acceleration of a magnitude 8 m/s²

To find : speed of the bald eagle after  the wind has blown for 3 seconds

Solution:

A bald eagle is flying with speed = 34 m/s

U = 34 m/s

causing it to slow down with a  constant acceleration of a magnitude 8 m/s²

=> a = - 8 m/s²

Using the formula

V = U  + at

U = 34 m/s

a =  - 8 m/s²

t = 3 Sec

V = velocity after 3 sec

V  = 34 + (-8)3

=> V = 34 - 24

=> V = 10 m/s

speed of the bald eagle after  the wind has blown for 3 seconds will be 10 m/s

Explanation:

Given A bald eagle is flying to the left with a speed of 34  meters per second when a gust of wind blows back  against the eagle causing it to slow down with a  constant acceleration of a magnitude 8 meters per second  squared. What will the speed of the bald eagle after  the wind has blown for 3 seconds ?

• Now we have initial velocity and final velocity.
• So acceleration a = v final – v initial / t
• So v final = v initial + a t
• Since the eagle is pointing towards left we have initial velocity as – 34 m / s
• So v final = - 34 + at
• Now as the eagle slows down acceleration will be positive.
• Therefore v final = - 34 + 8 t
• Now the time interval is given as 3 secs
• So v final = - 34 + 8 m / s^2 (3 s)
•                = - 34 + 24
• Or v final = - 10 m / s

Since speed cannot be negative and is always positive we get final speed as 10 m / s
