Section 13.5 Gravitational Potential Energy 15. An astronaut on earth can throw a ball straight up...
An astronaut on earth is able to throw a ball straight up to a height of 10.6 m. When the same astronaut travels to an unknown planet and throws the same ball straight up, the ball is able to reach a height of 52.1 m. What is the acceleration due to gravity on this unknown planet?
I throw a ball straight up in the air with a speed of 15 m/s. It leaves my hand at a height of y = 0 m. a) How high will it go? b) How long does it take to return to its initial height?
A ball is thrown straight up into the air. At what position is its kinetic energy a maximum? At what position is the gravitational potential energy of the ball-Earth system a maximum? Select the correct One: - At its maximum height the kinetic energy is maximum and the potential energy is minimal - In the middle of their trajectory both energies are maximum - At maximum height the kinetic energy is minimal and the potential energy is maximum - In...
You throw a ball straight up from the ground (? = 0) with an initial speed of 20 m/s. At the same time (? = 0), another ball is dropped from a building that is 15 m high. How long will it take for the two balls to be exactly the same height off the ground?
You throw a 0.29-kilogram ball straight up. If the ball reaches a height of 138 cm, what is the work done on the ball by the gravitational force?
1. Games in Space: On Earth, an astronaut throws a ball straight upward, and it stays in the air for a total of 3.0s before they catch it at the same height they released it. On the Moon, acceleration due to gravity is1/6 the value on Earth. If the astronaut repeats this process on the Moon, giving the ball the same initial speed, how much time would pass before they catch it?
A ball is thrown straight up such that it leaves your hand with 200 Joules of kinetic energy. Suppose we choose the ball + Earth as our system and we use the height of the ball when it leaves your hand as h = 0. Answer the questions below ignoring air resistance. Initial gravitational potential energy when the ball leaves your hand = Kinetic energy when the ball is half way to its maximum height = j. Gravitational potential energy...

A cat's crinkle ball toy of mass 35 g is thrown straight up with an initial speed of 7 m/s. Assume in this problem that air drag is negligible. (a) What is the kinetic energy of the ball (in J) as it leaves the hand? (b) How much work is done (in J) by the gravitational force during the ball's rise to its peak? (c) What is the change in the gravitational potential energy of the ball (in J) during...
You throw a ball straight up. The ball has an initial speed of 11.2 m/s when it leaves your hand. A) What is the maximum height the ball reaches relative to the throwing point. B) How long does it take the ball to reach this height? C) What is the position of the ball at t=2s? D) At what height does the ball have a speed of +5m/s?
