A ball is thrown straight upward and rises to a maximum height of 19 m above its launch point. At what height above its launch point has the speed of the ball decreased to one-half of its initial value? ____m
A ball is thrown straight up with an initial speed of 14.3 m/s. At what height above its initial position will the ball have one-half its initial speed? height:
A ball is thrown straight up with an initial speed of 13.7 m/s. At what height above its initial position will the ball have one‑half its initial speed?
An object is thrown vertically and has an upward velocity of 18 m/s when it reaches one fourth of its maximum height above its launch point. What is the initial (launch) speed of the object?
1. A ball is thrown straight up and passes point at a height of 40 m above its starting point in 5 s. What was its initial speed?
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 0.36-kg ball is thrown vertically upward with an initial speed of 12.5 m/s. What is the potential energy of the ball when it has travelled two-thirds of the distance to its maximum height? (Use the launch point to be the zero reference point of measurements of the heights)
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 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 1.2 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...
