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?
You throw a 0.29-kilogram ball straight up. If the ball reaches a height of 138 cm,...
You throw a ball straight up, and it reaches a height of 22 m above your hand before falling back down. What was the speed of the ball just after it left your hand? m/s
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?
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?
43. Analyze You throw a ball straight up into the air. ches a maximum height and returns to your hand. what location(s) is the kinetic energy of the ball (a) a maximum and (b) a minimum? At what location(s) is the potential energy of the ball (c) a maximum and (d) a minimum? At
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...
Section 13.5 Gravitational Potential Energy 15. An astronaut on earth can throw a ball straight up to a height of 15 m. How high can he throw the ball on Mars?
5. You throw a ball straight up from the ground level to a height of 10 ft. The ball falls down and hits the floor. It then bounces back to a height that is 8 ft and repeatedly bouncing up and down indefinitely, each time reaching a height four-fifths of the previous height. (a) When the ball hits the ground the first time, we call this the first hit. Find the height of the ball on the fifth hit. (b)...
throw a ball straight up into the air with initial velocity vi. (neglect air resistance). how long will it take for the ball to come back to its initial position? what is the maximum height the ball reaches?
1. To find the height of an overhead power line, you throw a ball straight upward. The ball passes the line on the way up after 0.80 s, and passes it again on the way down 1.2 s after it was tossed. (a) What is the height of the power line? (b) What is the initial speed of the ball?
