Need some help.
Worked out problems: Solve completely algebraically before inserting any values. Make sure your algebraic answer is in terms of given variables 5. A rock is thrown over a cliff from the origin with initial velocity +z points in the upward direction. where is it a time later? Ve,+o where A. (4 points) List two assumptions that you need to make to solve this projectile motion problem. B. (8 points) For the initial velocity, = 3 Isi-24, +2.02; where is the rock 2.0 s later? C. (8 points) If the ground is 65 m below the cliff, when will the rock hit the ground? Use the same initial velocity as in part B.
