In the question number 59, the time taken by the ball to reach the ground is
Text Solution
Verified by ExpertsThe correct answer is:
C
Let 
be the time taken by the ball to reach the highest point.
Here , 
As v = u +at
0 = 20 + (-10 ) 
or 
= 2s
Taking vertical downward motion of the ball from highest point to ground.
Here , u = 0, a = + g = 
s= 20 m + 25m = 45m 
As 
Total times taken by the ball to each the ground.
