1. When will you say a body is in (i) uniform acceleration? (ii) non-uniform acceleration? 2. A bus decreases its speed from 80 km h�1 to 60 km h−1 in 5 s. Find the acceleration of the bus.

A body is said to have uniform acceleration when there is equal change in velocity in equal interval of time
A body is said to have non uniform acceleration when there is unequal change in velocity in equal interval of time
v=60 km/hr
u=80 km/hr
t=5s
v= u+ a×t
60=80+ a×5
-20= a×5
a= -20/5
a= -4 km/hr^2

- Uniform Acceleration : A body is said to be in uniform acceleration if it travels with equal velocity in equal interval of Time.
- Non-Uniform Acceleration : A body is said to be non-uniform acceleration if it travels with unequal velocity in equal interval of time.
3)
Given :
- Initial velocity (u) = 80 km/h = 22.2
- Final velocity (v) = 60 km/h = 16.6
- Time (t) = 5s
