How long does it take the red ball to reach the ground

Reference no: EM13700399

Compute all parts of given question:

Question: A red ball is thrown down with an initial speed of 1.1 m/s from a height of 28 meters above the ground. Then, 0.5 seconds after the red ball is thrown, a blue ball is thrown upward with an initial speed of 25.3 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/s2.

Part A: What is the speed of the red ball right before it hits the ground?

Part B: How long does it take the red ball to reach the ground?

Part C: What is the maximum height the blue ball reaches?

Part D: What is the height of the blue ball 1.9 seconds after the red ball is thrown?

Part E: How long after the red ball is thrown are the two balls in the air at the same height?

Please show me how work it out above question.
