A particle is projected up along a rough inclined plane of inclination 45^ with the horizontal. If the coefficient of friction is 0.5 , the acceleration is ( g= Acceleration due to gravity )
Options
- Ag 2
- Bg 2 2
- C3 g 2 2
- Dg 2
Correct answer
C. 3 g 2 2
Step-by-step solution
Acceleration of an object up a rough inclined plane aligned a & =g( + )=g ( 45^ +0.5 45^ ) & =g ( 1 2 + 1 2 1 2 )= g 2 (1+ 1 2 )= 3 g 2 2 aligned
