- In the sport of billiards, event organizers often remove one of the rails on a pool table to allow players to measure the speed of their break shots (the opening shot of a game in which the player strikes a ball with his pool cue). V. o h d The top of a pool table is a height h = 3.25 ft from the floor. If a player's ball lands a distance d 14.75 ft from the table edge, what is her break shot speed vo? 12.3 Vo = mph Incorrect At what speed v did her pool ball hit the ground? 4.21 mph = IncorrectHelpA physics 151 student at the top of a building drops water balloons from the edge. A stop watch indicates it takes 1.20 seconds for the balloon to hit the ground. In units of feet how tall is the building? Round final answer to 2nd decimal places. At the end of the problem you must state which direction you choose to be positive.
- A sinx is the mathematical model for the hypothesis given for the time of flight of a projectile as a function of angle. A: the fit parameter A...A = 2V0 B: the fit parameter B...B = B was not used in the model make a plot of the time of flight for a projectile as a function of launching angle, with v0 = 3.92 m/s...which graph most matchJoanna travels north 5 miles and then goes west 3 miles before coming straight back south 2 miles. What is her displacement?A cannonball is shot with an initial speed of 66 m/s and 37.0º angle with respect to the ground. How long does it take for the ball to reach its the maximum height, in seconds? Use g = 10.0 m/s2. Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
