Answer:
2.84403 seconds
2.91483 seconds
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 9.81 m/s²
It takes 2.84403 seconds to reach the highest point
The ball will travel 39.67431+2 = 41.67431 m while going down to the ground
The ball takes 2.91483 seconds to hit the ground after it reaches its highest point.
