To find the height of an overhead power line, you throw a ball straight upward. The ball passes the line on the way up after 0.70 s, and passes it again on the way down 1.2 s after it was tossed
What is the height of the power line?
What is the initial speed of the ball?
I have just started spring term physics and was doing okay on this homework assignment till i got to this last problem. I am guessing that the force of gravity will play a role, but am stuck at where to start
Thanks so much
