    A rock dropped from a cliff using speed of sound

    Getting warmer...t1+t2=5.1s, so t2=5.1-t1. I therefore can substitute in 340(t2) as 340(5.1-t1)=4.9(t1^2)

    A rock dropped from a cliff using speed of sound

    Okay, so i took the time to look over this problem and separated the problem into two parts. I let d be my distance, so d = (0)(t1) + 1/2(9.8)t1^2. t1 being my first time. I then took d = vt and used the speed of sound for this problem, so d = (340m/s)(t2). t2 being my second time. i then made...

    A rock dropped from a cliff using speed of sound

    Homework Statement A rock is dropped from a sea cliff and the sound of it striking the ocean is heard 5.1 s later. If the speed of sound is 340 m/s, how high is the cliff? Homework Equations d=v/t(didnt work) The Attempt at a Solution My first attempt at this problem was to try...
