A ball is thrown from the top of a tower at a velocity of 15 m/sec. The ball hit the ground 5 seconds later. How high is the tower?

and

A rocket is fired straight up from a 60 ft. platform with an initial velocity of 96 ft/sec.
Find the number of seconds required to reach the maximum height. Find the maximum height

This should actually be in physics department and isn't algebra unless you left a lot of things out.

anonymous · Answer

nope i didnt leavee anything out
and its from my algebra 2 course unit 10
its an online course

anonymous · Answer

velocity =root(2 *9.8 *helght)  use that

anonymous · Answer

well........this is for my friend
cuz im a 7th grader in algebra 1 for the summer course
idk this stuff yet

If it's trown downwards at that speed it's 15m/sec*5sec.  So that's 75m.

For the other one, you don't use the metric system so shame on you.
