The defenders of a castle throw rocks down on their attackers from a 14 m high wall. If the rocks are thrown straight down with an initial speed of 6 m/s, hoe much faster are they moving when they hit the ground than if they were simply dropped? (m/s)
b.) if they throw the rocks straight up instead of straight down, how much faster are they moving than if they were just dropped? (m/s)
The answer may not be exact because of the approximated value used like 4.569 approximated to 4.57 . Again the value of g used is 9.8 but you can use it 10 also. Still if you encounter with any issues let me know in the comment below.
