U=. 0. final velocity V = 54×5/18=15m/S
a= v- u/t. =15- 0/15 =1m/s2
a= v- u/t. =15- 0/15 =1m/s2
Haha so simple. What a fool who asked this question...

1.a . velocity: the rate of change of displacement of a body with the passage of time. velocity = displacement \ time
acceleration: acceleration is a measure of the change in the velocity of an object per unit time. acceleration is represented by 'a'. acceleration = change in velocity \ time.
b. retardation:negative acceleration is called retardation
c. uniform acceleration:a body has uniform acceleration if its velocity increases by equal amount in equal interval of time eg. freely falling bodies
non uniform acceleration: a body has non uniform acceleration if its velocity increases or decreases by unequal amount in equal interval of time
