Question

With the help of a suitable example, elaborate the concept of - (a) Instantaneous velocity (b) Retardation. ​​

Answer 1

Answer:

If the displacement of the particle varies with respect to time and is given as (6t2 + 2t + 4) m, the instantaneous velocity can be found out at any given time by: s = (6t2 + 2t + 4)

Retardation is the opposite of acceleration. It is the rate at which an object slows down. Retardation is the final velocity minus the initial velocity, with a negative sign in the result because the velocity is dropping. The formula for acceleration can be used, recognizing that the final result must have a negative sign. And if time is also given then retardation = (final velocity - initial velocity) / time.
