A block is sliding down on an inclined plane of slope and at an instant t=0 this block is given an upward momentum so that it starts moving up on the inclined surface with velocity u . The distance (S) travelled by the block before its velocity become zero, is _ _ _ _ . ( g= gravitational acceleration)

Options

  1. A2 u²
  2. Bu² 2 g
  3. Cu² 2 g
  4. Du² 2 g

Correct answer

B. u² 2 g

Step-by-step solution

a = -g V^2 = U^2 + 2as 0 = u^2 - 2g s s = u^2 2g
