ANSWER:
Solution 10E
Step 1 of 4:
First we need to find, time taken to fall past the ledge to calculate the horizontal velocity to miss the ledge.
To calculate the the time taken,
As there are no forces acting in the horizontal direction, there will be no horizontal acceleration (F=ma) and hence the horizontal component of velocity will be constant
By fundamental relation,
Velocity=
