Ok I think it's becoming clearer. I was going off of your first reply that T is the time interval between the launching of the rocks, and may have gotten confused from that. I now understand that T is the time in which they collide. Clearly, Rock1 is in the air longer because it was thrown...

Ok. I still assumed that d1=d2. V01t1+(1/2)gt12= V02(T+t1)+(1/2)g(T+t1)2

I defined them as the times that the rocks were thrown.

Oh. I see what's going on. So I drew a graph just to help me visualize, where I assumed arbitrary times, where the first rock is thrown at 1s and the second is thrown at 4s. The time interval between them is 3s. This helped me confirm the equation that T=t2- t1, which means that t2=t1+T

Homework Statement This is a quiz question that was given in my AP physics C class. "A rock is launched upward with a speed V0. With what velocity must a second rock be launched from the same initial position at time T later so that it hits the first rock when it has a velocity of -V0/2."...

Thank you very much. I will definitely consider doing this.

Thanks guys. I've also been considering self studying calculus, but have been told that it's very risky because I might teach myself incorrect concepts and get into the habit of using those incorrect concepts. I don't have the choice to take ap physics 1 and I haven't been accepted to take ap...

Hi. I've been pondering on this decision lately. I'm a Junior in high school and have been accepted to take AP physics C for senior year starting with my fall semester next school year. I really want to pursue a physics/ engineer related major, but here's the thing. I'm aware that AP physics C...
