Question

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-' to 60 km h-' in 5 s.
Find the acceleration of the bus.
3. A train starting from a railway
station and moving with uniform
acceleration attains a speed
40 km h-' in 10 minutes. Find its
acceleration.​

Answer 1

Answer:

Explanation a body will be in uniform acceleration when acceleration is not changing with time and vice versa in case of non uniform acceleration

For finding acceleration apply

V=u+at

But remember time given is in second and velocity is given in km/hrs so do conversion
