A) A stone is thrown directly upward with an initial speed of 7.9 m/s from a height of 19 m.
What is the speed of the stone in m/s when it hits the ground?
Use g = 9.8 m/s2
Enter a number with 2 digits behind the decimal point.
B) Consider motion in one dimension. (The sign of the vector
quantities is their direction indicator.)
An object moves in the positive x-direction with speed 3.6 m/s for
2 s. It stops for 2.1 s and then accelerates with acceleration -5.3
m/s2 for 2.5 s.
What is the average velocity of this object in units of m/s?
Enter a number with two digits behind the decimal point.

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...
