An aeroplane accelerates from rest at a rate
of 25m/s² for 3 s .calculate final velocity

The final speed is 75 m/s

Explanation:

Constant Acceleration Motion

It's a type of motion in which the velocity of an object changes uniformly in time.

Being a the constant acceleration, vo the initial speed, vf the final speed, and t the time, the following relation applies:

The airplane comes from rest (vo=0) accelerating at a=25 m/s^2 for t=3 s.

The final speed is:

The final speed is 75 m/s
