Two students are on a balcony a distance h above the street. One student throws a ball vertically downward at a speed vi; at the same time, the other student throws a ball vertically upward at the same speed. Answer the following symbolically in terms of vi, g, h, and t. (Take upward to be the positive direction.) (a) What is the time interval between when the first ball strikes the ground and the second ball strikes the ground? Δt...
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 person on a platform above the ground throws a ball upward at 6 feet per second. It takes 3 seconds for the ball to reach the ground below the platform. Determine the platform height above the ground. Also determine the balls speed as it strikes the ground. Assume the ball was released at the level of the platform A person on a platform above the ground throws a ball upward at 6 feet per second. It takes 3 seconds...
Two stones are thrown vertically upward from the ground, one with three times the initial speed of the other. Assume free fall. If the faster stone takes 11.0 s to return to the ground, how long will it take the slower stone to return? If the slower stone reaches a maximum height of H, how high (in terms of H) will the faster stone go?

Spider-Man launches himself from the ground so that he travels vertically upward, eventually catching hold of a hovering helicopter that is 420 m above the ground. Assume air resistance is negligible as he ascends. (g = 9.8m/s) » What minimum initial takeoff speed must Spider-Man have to reach the helicopter?

A mischievous SUOC student has climbed on the roof of a snow-covered building and is trying to hit her friend with snowballs as he walks through the Quad. She throws them at an angle of 20◦ above the horizontal at a speed of v0 = 5 m/s. The building has a height h = 6 m. He decides to throw a snowball back at her. He’s standing a distance d from the side of the building, and throws a snowball...
2. A water balloon is thrown upward from a window 25 m above the ground and hits the ground 2.95 s later. What's the maximum height above the window that the balloon reaches? a) 3.77 m b) 2.59 m c) 2.21 m d ) 1.82 m e) 1.17 m 400 m 3. A student who can swim with a speed of 2.5 m/s in still water wants to get to the other side of a 400 m wide river whose...
Two stones are thrown vertically upward at the same instant of time with the same initial speed, Vo= 6.00 m/s. One is from the surface of the earth and the other from the surface of Mars. Note that on the surface of Mars, g is 3.73 m/s A) The maximum height achieved is greater on Mars..................TorF B) What is the maximum height on the Earth?
