You throw a ball straight up from the ground (? = 0) with an initial speed of 20 m/s. At the same time (? = 0), another ball is dropped from a building that is 15 m high. How long will it take for the two balls to be exactly the same height off the ground?

A ball is thrown upward from the ground with an initial speed of 16.6 m/s; at the same instant, another ball is dropped from a building 20 m high. After how long will the balls be at the same height above the ground?
A ball is thrown upward from the ground with an initial speed of 20.2 m/s; at the same instant, another ball is dropped from a building 20 m high. After how long will the balls be at the same height?
A ball is thrown upward from the ground with an initial speed of 20.0 m/s; at the same instant, another ball is dropped from a building 12 m high. After how long will the balls be at the same height?
I throw a ball straight up in the air with a speed of 15 m/s. It leaves my hand at a height of y = 0 m. a) How high will it go? b) How long does it take to return to its initial height?
A ball is thrown straight up from the edge of the roof of a building. A second ball is dropped from the roof a time of 1.14 s later. You may ignore air resistance. Part A If the height of the building is 21.0 m, what must the initial speed be of the first ball if both are to hit the ground at the same time? m/s Submit Request Answer Incorrect; Try Again; 3 attempts remaining Part B Consider the...
You throw a ball straight up. The ball has an initial speed of 11.2 m/s when it leaves your hand. A) What is the maximum height the ball reaches relative to the throwing point. B) How long does it take the ball to reach this height? C) What is the position of the ball at t=2s? D) At what height does the ball have a speed of +5m/s?
Two throw A blue ball is thrown upward with an initial speed of 22.2 m/s, from a height of 0.8 meters above the ground. 2.7 seconds after the blue ball is thrown, a red ball is thrown down with an initial speed of 9.2 m/s from a height of 27.8 meters above the ground. The force of grandly due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s^2. What is the speed of...
Standing on the roof of a 61 m tall building, you throw a ball straight up with an initial speed of 19.5 m/s. If the ball misses the building on the way down, how long will it take from you threw the ball until it lands on the ground below? Give your answer in seconds and round the answer to three significant figures.
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...
Q) Ball A is thrown straight up with an initial velocity V0 from a cliff of height h above ground, where h is not known. at the same time ball B is dropped from the same cliff. the time of flight of ball B is 1/4 that of ball A. take the upward direction is positive and A) draw a single V vs. t plot for both balls. B) draw a single position vs. time plot for both the balls....
