A ball is thrown straight upward and returns to the thrower's hand after 3.20 s in the air. A second ball is thrown at an angle of 39.0° with the horizontal. At what speed must the second ball be thrown so that it reaches the same height as the one thrown vertically? _____m/s
A ball is thrown straight upward and returns to the thrower's hand after 2.30 s in the air. A second ball is thrown at an angle of 39.0° with the horizontal. At what speed must the second ball be thrown so that it reaches the same height as the one thrown vertically?
A student throws a ball vertically upward such that it travels 6.8 mm to its maximum height.If the ball is caught at the initial height 2.7 ss after being thrown, what is the ball’s average speed?
A ball is thrown straight upward and returns to the thrower's hand after 2.05 s in the air. A second ball thrown at an angle of 31.0° with the horizontal reaches the same maximum height as the first ball. (a) At what speed was the first ball thrown? m/s (b) At what speed was the second ball thrown? m/s
A 0.44-kg ball is thrown vertically upward with an initial speed of 16.5 m/s. What is the kinetic energy of the ball when it has travelled three-quarters of the distance to its maximum height?
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...
At t = 0 s, a ball B1 is thrown vertically upward with a speed of 30 m/s. When B1 is 25 m above ground on the way up, a second ball B2 is thrown vertically upward from the ground with a speed of 40 m/s (Take the magnitude of the acceleration due to gravity g =10m/s2) a) How many seconds after B1 was B2 thrown upward?
Free-fall notion 1. A ball is thrown vertically upward at an initial speed of 49 m/s. Assume that the ball leaves the hand when it is 15 m above the ground (about the height of Kirkbride), and that the effects of air resistance can be ignored. Choose your landmark to be the ground; then at t -0, yo- +15 m, Vyo +49 m/s a. 5 pts) How fast is the launch speed in mph? Do you think this is a...
Two identical balls are thrown vertically upward. The second ball is thrown with an initial speed that is twice that of the first ball. How does the maximum height of the two balls compare? The maximum heights of the two balls are equal. The maximum height of the second ball is two times that of the first ball. The maximum height of the second ball is four times that of the first ball. The maximum height of the second ball...
