Answer to Question #72123 in Mechanics | Relativity for PREETISH KUMAR CHANDA

Question

If a = v^1/2, then at t =0 and at v = 0 find initial velocity(u) ?

Answer 1

Solution:
Acceleration: a=dv/dt=v^(1/2)
Then, by integrating: dv*v^(-1/2)=dt→2v^(1/2)=t (v(t=0)=0)
So, v(t)=t^2/4
Initial velocity: v(0)=0 (as its said in question)

Answer: 0
