A juggler performs in a room whose ceiling is a height 2.5 m above the level of his hands. He throws a ball upward so that it just reaches the ceiling. a)What is the initial velocity of the ball? b)What is the time required for the ball to reach the ceiling? c)At the instant when the first ball is at the ceiling, he throws a second ball upward with two-thirds the initial velocity of the first. How long after the...

Two identical balls are thrown vertically upward. The second ball is thrown with an initial speed that is twice that of the first ball. How does the maximum height of the two balls compare? The maximum heights of the two balls are equal. The maximum height of the second ball is two times that of the first ball. The maximum height of the second ball is four times that of the first ball. The maximum height of the second ball...

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...

Two Thrown Balls 1 2 3 45678 A blue ball is thrown upward with an initial speed of 19.8 m/s, from a height of 0.6 meters above the ground. 2.4 seconds after the blue ball is thrown, a red ball is thrown down with an initial speed of 8.9 m/s from a height of 22.3 meters above the ground. The force of gravity due to the earth results in the bals each having a constant downward acceleration of 9.81 m/s2....

Review Two small plastic balls hang from threads of negliglble mass. Each ball has a mass of 0.140 g and a charge of magnitude g. The balls are attracted to each other, and the threads attached to the balls make an angle of 20.0 with the vertical, as shown in the figure.(Figure 1) Figure 1 ot 1 20.0 20.09 205 cim Part A Find the magnitude of the electric force acting on each ball.

Two balls are separated by an some vertical distance h (in meters) from each other. The first ball is thrown down with an initial velocity voi = -3.0 m/s and the other one is thrown up from the ground with an initial velocity vo2 = 3.0 m/s at the same time the other is thrown. How far, in meters, must they be separated so they hit the ground at the same time?

1. A ball is thrown horizontally from the roof of a building 9.4m tall and lands 9.7m from the base. What was the balls initial speed? 2. You buy a plastic dart gun, and being a clever physics student you decide to do a quick calculation to find its maximum horizontal range. You shoot the gun straight up, and it takes 3.6s for the dart to land back at the barrel. What is the maximum horizontal range of your gun?...
