Acceleration is -9.8 m/s^2. Answer 11 and 12 and show your work.

11. Two identical baseballs are taken to the top of a 200-meter high cliff. One ball is thrown upwards from the top in such a way that it will pass the starting point and travel all the way to the ground below. The second ball is dropped from the top at 3.50 seconds after the first ball is thrown. If the two balls hit the ground below at the exact same time with what velocity was the first ball thrown?

12. A ball is thrown upwards from ground level with an initial velocity of 80 m/s. How long will it take the ball to reach the height of 175 meters above the ground as it comes back down from its peak?

2) A ball is dropped from rest at the top of a high cliff. It takes 10.00 seconds for the ball to reach the ground below. Find: a) the height of the cliff, b) the velocity of the ball hitting the ground below, c) the time it takes for the ball to fall half of the cliff's height, and d) the velocity at this halfway point. (Remember acceleration due to gravity is -9.800 m/s^2).

At t = 0, Ball 1 is dropped from the top of a 19 mm-high building. At the same instant Ball 2 is thrown straight up from the base of the building with an initial velocity of +12 m/sm/s. Assume that Ball 1 starts from rest and that air friction can be ignored. At what height will the two balls pass each other? What is the velocity of each ball at the moment they are at the same height?  Express...
