I think I have it now. 1/2at12=ct2 and t1= t-t2 Then solve quadratic equation with a=1; b= -71.4; c=23.04 Thank you so much!

You give me wonderful ideas on how to start solving physics problems effectively, but I need so much more practice. This time I got: T2= 2h/a + h2/c2 however, I still can't get it. It's always so close. I don't know what more to ask you, I think you've told me all that you could...

Thank you. I have : -1/2aT12 = c(4.8-T1) I still can't find the answer.

I don't have the distance.

Hello, I'm calculating a physics problem and I'm supposed to calculate the height of a building given that: rock is dropped from the building, the sound of the rock hitting the ground is heard 4.8s later, the speed of sound is 350m/s, and I don't know how do I calculate the time since...
