Explanation:
Answer:
(a) 
(b) 
Explanation:
We will take ground level as origin and upward is positive direction
the givens are

Part (a)
To find the final velocity we use the kinematic equation
So

Part (b)
To find time of rock trip until it touches the ground we will use simple kinematic equation or simple motion equation

Notice that we substituted vf with negative sign because its direction is downwards
