Question

Find retardation when change in velocity is - 25m/s for a time of 20 second​

Answer 1

Answer:

1.25m/²

Explanation:

Acceleration(a) or Retardation(-a) = Velocity/time.

-a = v/t = 25/20 = 5/4 = 1.25m/s²

Since it has asked retadation so it will be 1.25 not -1.25.

As -1.25 is for acceleration.
