29.(a) When will you say a body is in (i) uniform acceleration? (ii) non-uniform acceleration?
(b) Express average velocity when the velocity of a body changes at a non-uniform rate and a uniform
rate.

Answer:
(a)(1)When a body is changing its velocity at a constant rate, then the body is said to be moving with uniform acceleration.
(2)When a body is changing its velocity at different rates, then the body is said to be moving with non-uniform acceleration.
(b)When the velocity of a body changes at a non-uniform rate, its average velocity is found by dividing the net displacement covered by the total time taken.
i.e . Average velocity = Net displacement / Total time taken
In case the velocity of a body changes at a uniform rate, then the average velocity is given by the arithmetic mean of initial velocity and final velocity for a given period of time.
i.e. Average velocity = Initial velocity + final velocity / 2
plz mark brainliest tyvm!!!
a body is said to be in uniform acceleration if the velocity of the body increases or decrease in a uniform rate.
a body is said to be in non uniform acceleration if the velocity of the body increases or decrease in a non uniform rate.
Average velocity = total displacement /total time
Average velocity = initial velocity + final velocity /2
