Question

The displacement of a particle in time t is given by s = at + bt². The initial velocity and acceleration are:
  1. A
    2b and a
  2. B
    a and b
  3. C
    a and 2b
    Correct
  4. D
    b and 2a

Correct answer

a and 2b

Explanation

Comparing with s = ut + ½(Acc)t²: u = a (initial velocity), ½ × Acc = b → Acc = 2b. So initial velocity = a, acceleration = 2b.
