[SOLVED] Acceleration/Velocity Problem 1. The problem statement, all variables and given/known data Two students, Anne and Joan, are bouncing straight up and down on a trampoline. Anne bounces 2.61 times as high as Joan does. Assuming both are in free-fall, find the ratio of the time Anne spends between bounces to the time Joan spends. 2. Relevant equations y=V(0)t+ (1/2)gt^2 3. The attempt at a solution Ok I figured that if Anne is jumping 2.61 times as high as Joan, I could set y (the displacement) as 2.61 for Anne and 1 for Joan. However I plugged the numbers into the equation and ended up getting a negative answer for my time, which doesn't make sense. Here's my equations that I used: Anne- 2.61=(1/2)(-9.8)t^2 -.53=t^2 Joan- 1=(1/2)(-9.8)t^2 -.204=t^2 I figured what I would do after i got the time is to multiple them both by 2 since I only calcuated them returning for the highest point to lowest point, then plugging them into a ratio. Any thoughts?
