A ball is thrown vertically upward with a speed of 40 ~m / s . The time taken by the ball to reach the maximum height would be approximately

Options

  1. A2 s
  2. B3 s
  3. C4 s
  4. D5 s

Correct answer

C. 4 s

Step-by-step solution

at h , v =0 Now, V=u+a t 0=40-g t aligned & gt =40 t 40 ~g & t = 40 10 =4 sec aligned
