Question

An object travels 16 m in 4 s and then another 16 m in 2 s. What is the average

speed of the object? When will you say a body is in

(i) uniform acceleration? (ii) nonuniform acceleration?​

Answer 1

The Answer Is :

If Object Travels from 16m 4s

and another 16m in 2s

Average will be 16 m 3s

Answer 2

1) When the velocity of a body changes by equal amount in an equal interval of time we can say that the body has a uniform acceleration. If the velocity of the body is increasing or decreasing equally in equal intervals of time, we can say that the body is accelerating uniformly.

2) A body is said to be in a non-uniform motion if it travels unequal distances in equal intervals of time. For example, if we drop a ball from the roof of a tall building, we will notice that it will cover unequal distances in equal intervals of time.
