ANSWER:

Solution 8DQ

Step 1:

(a).Consider the energy conservation principle to calculate greatest speed of the ball at bottom

${U}_{i}+{K}_{i}={U}_{f}+{K}_{f}$

Here U and K are the potential and kinetic energy of the ball at initial and final stage.

Where ${U}_{i}=mgh$ and ${K}_{i}=0$

${U}_{f}=0$ and ${K}_{f}=1/2\ m{v}^{2}$

$mgh=$ ½ $m{v}^{2}$

$v=\sqrt{2gh}$

Here m is mass of ball,g is gravity and h is height.

Hence,the bottom speed of ball in all cases same that is $\sqrt{2gh}$ .
