Thanks for the answer and the push for me to do well on the problem.

I have a question that could make me seem potentially stupid. Is it feasible to utilize electric currents to split ocean water into hydrogen and oxygen for the desalinization of ocean water and providing oxygen for submarines

Okay, and thanks for the help. Physics is not my forte.

it traveled approximately 30.66 meters into the air and its final velocity before striking the ground was 17.34

is this right? displacement = (initial velocity)(change in time) + 1/2(acceleration)(change in time)^2 0 = x(5) + 1/2(-9.81)(5)^2 approximately 24.5 m/s ?

I thought about that as soon as I posted, well about the displacement being zero, and the 10 was a typo.

You know how to do it, but you just want me to try? Well this is what I thought but I am unsure if it is right. its original and final velocity will be 0 and that it takes 2.5 seconds to reach its maximum height and 2.5 more seconds to hit the ground. I think Does this make sense at all...

Okay, so! My physics is lacking, but my life sciences are excellent, but that won't save me. How do I determine object's acceleration and velocity when it strikes the ground given: An object is thrown up into the air and then falls back to earth, remains in the air for 5 seconds before...

Does this make sense at all? displacement = initial velocity(change in time) + 1/2(acceleration)(change in time)^2 so x = 0(10) + 1/2(9.81)(10)^2 ?

my teacher hinted at the fact that its original and final velocity will be 0 and that it takes 2.5 seconds to reach its maximum height and 2.5 more seconds to hit the ground. I think that is what she said.

that is all the information that was given.

Okay, so! My physics is lacking, but my life sciences are excellent, but that won't save me. How do I determine how long an object remains in the air and its velocity when it strikes the ground given: An object is thrown up into the air and then falls back to earth, remains in the air for 5...
