A cardboard strip, bent in the shape of the letter C, is put on a rough inclined plane, as shown in the figure. What should be the time taken to travel a distance a if the inclined plane is made completely smooth? [Take angle of inclined plane as α]

Options:

Answer:

Solution:

The acceleration is $a_{n} = g sin α$ .

Thus, $a = \frac{1}{2} g sin α t^{2}$ , which means $t = \frac{2 a}{g s i n α}$ .
