a helicopters speed increases from 25m/s to 60 m/s in 5 seconds. what is the acceleration of the helicopter?

The acceleration of the helicopter can be calculated using the formula:

Acceleration (a) = Change in velocity (Δv) / Time taken (Δt)

Given:
Initial velocity (u) = 25 m/s
Final velocity (v) = 60 m/s
Time taken (Δt) = 5 seconds

To find the change in velocity (Δv), we subtract the initial velocity from the final velocity:

Δv = v - u = 60 m/s - 25 m/s = 35 m/s

Now we can substitute these values into the formula to calculate the acceleration:

Acceleration (a) = Δv / Δt = 35 m/s / 5 s = 7 m/s^2

Therefore, the acceleration of the helicopter is 7 m/s^2.
