If a ball was thrown straight down from 15 meters above the ground at 20 meter per second. At what speed will the ball hit the ground.
A blue ball is thrown upward with an initial speed of 24.1 m/s, from a height of 0.8 meters above the ground. 2.9 seconds after the blue ball is thrown, a red ball is thrown down with an initial speed of 10.4 m/s from a height of 31.4 meters above the ground. The force of gravity due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s2. What is the height of the red...
A red ball is thrown down with an initial speed of 1.3 m/s from a height of 26 meters above the ground. Then, 0.4 seconds after the red ball is thrown, a blue ball is thrown upward with an initial speed of 23.9 m/s, from a height of 1 meters above the ground. The force of gravity due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s2. What is the speed of the...
A blue ball is thrown upward with an initial speed of 23.9 m/s, from a height of 0.5 meters above the ground. 2.9 seconds after the blue ball is thrown, a red ball is thrown down with an initial speed of 7.5 m/s from a height of 31.5 meters above the ground. The force of gravity due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s^2. How long after the blue ball is...
A blue ball is thrown upward with an initial speed of 22.8 m/s, from a height of 0.6 meters above the ground. 2.8 seconds after the blue ball is thrown, a red ball is thrown down with an initial speed of 7.7 m/s from a height of 28.2 meters above the ground. The force of gravity due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s2. ) What is the speed of the...
A red ball is thrown down with an initial speed of 1.2 m/s from a height of 25 meters above the ground. Then, 0.6 seconds after the red ball is thrown, a blue ball is thrown upward with an initial speed of 23.8 m/s, from a height of 0.8 meters above the ground. The force of gravity due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s^2. 1)What is the speed of the...
A blue ball is thrown upward with an initial speed of 20 m/s, from a height of 0.8 meters above the ground. 2.4 seconds after the blue ball is thrown, a red ball is thrown down with an initial speed of 5.3 m/s from a height of 22.4 meters above the ground. The force of gravity due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s2. 1) How long after the blue ball...
