Answer to Problem 5MS
The time after which the ball opposite a roof
Explanation of Solution
Given information:
The initial speed(r) of ball=19.6 m/s
Height of roof =
Calculation:
Let, the time taken by ball to opposite the root top=t
Given initial speed(r) of ball=19.6 m/s
Putting the values of
Dividing both sides of the equation by 4.9:
Factorizing by splitting the middle term:
Either,
Either,
Hence, the time after which the ball opposite a roof
