A particle starts with an initial velocity of 10 . 0 ms - 1 along x -direction and accelerates uniformly at the rate of 2 . 0 m s - 2 . The time taken by the particle to reach the velocity of 60 . 0 m s - 1 is _____.

Options

  1. A25   s
  2. B3   s
  3. C6   s
  4. D30   s

Correct answer

A. 25   s

Step-by-step solution

The given data is v = 60   m   s - 1 u = 10   m   s - 1 a = 2   m   s - 2 Using the equation v = u + a t , we get 60 = 10 + 2 t ⇒ t = 60 - 10 2 ⇒ t = 25   s
