Given:
A block is projected along a rough inclined plane making an angle of 30degree with the horizontal.
To Find:
Obtain coefficient of friction between the block and the plane if the time
of ascent is half the time of descent?
Solution:
here, according to question; a block is projected along a rough inclined plane,
therefore,
from equation of motion;
when block slide down then,
Since, it is given that- time of ascent is half the time of descent.
therefore,
Hence, coefficient of friction is 0.346
