A body sliding on a smooth inclined plane required 4s to reach the bottom, starting from rest at the top. How much time does it takes to cover one-fourth the distance starting from rest at top?

(b) Using $t = \sqrt{\frac{2h}{a},}t \propto \sqrt{l},\frac{t_{2}}{t_{1}} = \sqrt{\frac{l/4}{l}} = \frac{1}{2}$
or $t_{2} = \frac{t_{1}}{2} = \frac{4}{2} = 2$s
