The initial velocity of a particle is u (at t= 0) and the acceleration a is given by alpha t3/2. Which of the following relations is valid?
1. v = u + αt3/2
2. v = u + 3/2αt3
3. v = u +2/5αt5/2
4. v = u + αt5/2
why to use integration in this question ​

Answer:

Explanation:

Given initial velocity =u, acceleration =αt  

3/2

 

Also we know  

dt /du =a

du=adt

Now integrating the above equation we get,

du=α∫  0  or t  t  3/2 dt

 v−u=  5/2  αt  2 /5

v=u+ 2 / 5  αt  5/ 2
