❤❤Hello,GOOD AFTERNOON EVERYONE ❤❤❤❤
Ques. A block is pushed upwards along the
roof forming an angle a with the horizontal.
The time of the ascent of the block to the
upper point was found to be half the time
of its descent to the initial point.
Determine the coefficient of friction lit
between the block and the roof.
Thanks in Advance
