Two students are on a balcony 19.1 m above the street. One student throws a ball vertically downward at 13.8 m/s. At the same instant, the other student throws a ball vertically upward at the same speed. The second ball just misses the balcony on the way down. What is the magnitude of the velocity of the first ball as it strikes the ground? Answer in units of m/s. What is the magnitude of the velocity of the second ball...

A boy standing on top of a building throws a small ball from a height of H1 = 39.0 m. The ball leaves with a speed of 12.5 m/s, at an angle of 65.0 degrees from the horizontal, and lands on a building with a height of H2 = 15.0 m. Calculate for how long the ball is in the air. (Neglect air friction, and use g = 9.81 m/s2.

A ball is thrown straight downward from the top of a building. Its initial velocity is 12 m/s downward. It hits the ground 1.2s after release. How tall is the building? *ignoring any air resistance* Please explain in detail why you need to solve for vf first using Vf=Vo+at and then plug Vf into Vf^2=Vo^2+2a(x2-x1) I assumed that since the ball hits the ground that vf=0m/s but using that I am getting the incorrect answer of 7.3m instead of the correct...

From the top of a 70 m building, you throw a ball straight up at 6 m/s. The ball misses the building on the way down. What is the maximum height of the ball? What is the velocity of the ball after 2 s? What is the final velocity of the ball (just before it hits the ground) Now, the ball is thrown straight down at 6 m/s. What is the velocity of the ball after 2 s? Using the initial...
