Multiple Choice Options

  • A (B), (C)
  • B (A)
  • C (A), (B), (C)
  • D (A), (B), (D)

Step-by-Step Verified Solution

Given initial velocity u = 0 and acceleration is constant
At time t
v = 0 + at
⇒\Rightarrow v = at

Also x=0(t)+12at2x = 0(t) + {1 \over 2}a{t^2}
⇒\Rightarrow x = 12at2{1 \over 2}a{t^2}

Graph (A), (B) and (D) are correct
