Question

Rectilinear Motion
Velocity of a body is given as a function of time as V = 15 + 2t . The body is undergoing
(B) Uniform motion
(D) Uniform acceleration
(A) Uniform retardation
Nonuniform acceleration

Answer 1

Answer:

Correct option is

C

Non-uniform acceleration

As velocity v=  

10

t  

2

 

​

+20

so the acceleration will be a=  

dt

dv

​

=  

10

2t

​

+0=t/5

That is acceleration is time dependent not uniform.

Option C is correct.
