A triangular wedge of mass ‘M’ is placed on a smooth horizontal surface. A block of mass ‘m’ is placed on the wedge. The coefficient of friction between the block and the wedge is 0.6. The horizontal acceleration ‘a’ of the wedge such that ‘m’ moves up the wedge is
Answers
Answer:
3
Step-by-step explanation:
3 is the correct answer
Answer:
The required acceleration is 23.2 m/s².
Step-by-step explanation:
Step 1: A triangular wedge ofmass 'M' is placed on a smooth horizontal surface. A block of mass 'm' is placed on the wedge. The coefficient of friction between the block and the wedge is 0.6.
Value of horizontal acceleration of the ways such that "m" moves up the wedge.
Step 2: First of all , look at the free body diagram of mass "m" attached in the photo.
At limiting conditions, (when the block is about to move up), we can say that :
Step 3: Putting values theta of mu and :
So, the required acceleration is 23.2 m/s².
