Question

The velocity of a body at the end of 5 sec is 30m/s, at the end of 12sec is 58 m/s and at the end of 22 sec it is 98 m/s. The body is moving with

Uniform velocity

Uniform acceleration

Uniform retardation

Uniform displacement

Answer 1

Since velocity is changing, the above situation is not uniform velocity.

a=(v-u)/∆t
a1=58-30/12-5
a1=4

a2=98-58/22-12
a2=40/10
a2=4

Since acceleration is the same a1=a2
the above situation is Uniform acceleration.

Since both are positive it is not uniform retardation
