A helicopter’s speed increases from 25 m/sec to 60 m/sec in 5 seconds. What is the acceleration of this
helicopter?

Sagot :

It increases by 60-25=35 m/s. Divide that by the time (5 seconds) to get [tex]7 m/s^2[/tex]

Answer:

7 m/s^2

Explanation:

Acceleration = Vf - Vi / t, where Vf is the final velocity, Vi is the initial velocity, and t is the time. It is given that the helicopter’s speed increases from 25 m/s to 60 m/s in 5 s, so Vf = 60 m/s, Vi = 25 m/s, and t = 5. When putting this into the equation you get 60 - 25 / 5 which can simplify to 35 /5 also known as 7 m/s^2.
