A helicopter speed increases from 25M/S to 60 amp/as five seconds. What is the acceleration of the helicopter?
To find the acceleration, we can use the formula:
Acceleration (a) = (change in velocity) / (time)
The change in velocity is given as the difference between the final velocity and the initial velocity:
Change in velocity = 60 m/s - 25 m/s = 35 m/s
The time taken for this change in velocity is given as 5 seconds.
Now we can substitute these values into the formula to find the acceleration:
Acceleration (a) = (35 m/s) / (5 s) = 7 m/s²
Therefore, the acceleration of the helicopter is 7 m/s².
