A body is projected up along a rough inclined plane of inclination 45^ . The coefficient of friction is 0.5 . Then the retardation of the block is

Options

  1. Ag 2 2
  2. Bg 2
  3. C3 g 2 2
  4. Dg 2

Correct answer

C. 3 g 2 2

Step-by-step solution

Retardation aligned &=g( + ) &=g ( 1 2 +0.5 1 2 ) &= g 2 (1+0.5) &= 1.5 g 2 = 3 g 2 2 aligned
