A block slides down on an incline of angle 30^ with an acceleration g 4 . Find the kinetic friction coefficient.
Options
- A1 2 2
- B0.6
- C1 2 3
- D1 2
Correct answer
C. 1 2 3
Step-by-step solution
Consider the situation Let the mass of block be m . The equation of forces aligned m g 30^ -f & = m g 4 f & = m g 4 aligned Also, N=m g 30^ =m g 3 2 As the block is slipping on the incline, friction is aligned _n & = F N = m g 4 m g 3 2 & = 1 2 3 aligned
