a rock is thrown horizontally with a speed of 17 m/s from a vertical cliff of height 34 m.
A- I solved for t=2.63
B-How far will it land from the base of the cliff?
im using x=xo+vox*t
i get -6.46 and it is wrong. What am I doing wrong?
C-What is the velocity (magnitude and direction counterclockwise from the +x-axis, which is the initial horizontal direction in which the rock was thrown) of the rock just before it hits the ground?
what would i use for a formula?
