Hello everyone, This is my first post so I am sorry if this is in the wrong section. I am currently in a rush to finish my homework. I have tried working on it for several hours but I still cannot figure it out. I am mainly trying to figure out how long the object will be in the air. A stone is thrown upward at a speed of 30m/s off the edge of a 40m tall tower. 1. How can I find the velocity of the stone versus time. The time is suppose to start at 0 and go up increments of 0.3 sec from when the stone is thrown to the time the stone hits the ground. Here are the equations I used: Final Velocity = Initial Velocity + Acceleration x Time Distance = Initial Velocity x Time + 0.5 x Acceleration x Time^2 Final Velocity^2 = Initial Velocity^2 + 2 x Acceleration x Distance I will have to graph this but I need to know how to find all the data first. Thank you for your help.
