A ball is kicked at an angle of 30 degrees to the horizon, with a horizontal speed of 33.9 m/s and a vertical speed of 19.6 m/s.
Vy = 19.6 m/s
30°
Vx= 33.9 m/s
Which answer best gives the horizontal distance the ball travels before
returning to its starting height?

Argon, neon, and xenon are examples of

Arigid tank is divided into two equal parts by a partition. one part of the tank contains 3 kg of compressed liquid water at 400 kpa and 60°c while the other part is evacuated. the partition is now removed, and the water expands to fill the entire tank. determine the entropy change of water during this process, if the final pressure in the tank is 40 kpa. use steam tables.

Two horses begin at rest. after a few seconds, horse a is traveling with a velocity of 10 m/s west, while horse b is traveling with a velocity of 13 m/s west. which horse had a greater acceleration? a. horse a because its change in velocity was greater than horse b's in the same time. b. horse b because its change in velocity was greater than horse a's in the same time. c. horse b because its change in velocity was the same as horse a's, but it took less time. d. both horses had the same acceleration.
