There is also another gas station 0.5 km due south of your house. You go to the first gas station and find out that it is closed. What direction and distance do you need to drive to get from the first gas station to the second one (assume you can do this in using a street that runs directly between the two)? A) 0.2 km west B) 0.366 km at 54.6 degrees south of west C) 0.58 km at 30.1 degrees south of west D) 0.5 km due southA projectile is launched at some angle to the horizontal with some initial speed v;, and air resistance is negligible. Select all statements about the projectile that are true. A) The projectile is a freely falling body. B) Vertical acceleration is 9.8 m/s2, upward. C) Vertical acceleration is 9.8 m/s2, downward. D) Vertical acceleration depends on the angle. E) Horizontal acceleration depends on vi. F) Horizontal acceleration is zero. G) Horizontal acceleration depends on the angle .A student wants to measure the muzzle velocity of a pellet shot from his gun. He mounts the barrel of the gun horizontally. He places a target board 5.0m in front of the gun. He then carefully marks the target with a spot where the pellet would strike if there were no gravity to change the pellet's path. He fires the gun. The pellet strikes the target exactly 0.25m below the marked spot. Calculate the muzzle (initial) velocity of the pellet as it leaves the gun. (Enter your answer)A landscape architect is planning an artificial waterfall in a city park. Water flowing at 1.30 m/s will leave the end of a horizontal channel at the top of a vertical wall 2.90 m high, and from there the water falls into a pool. She tells the city that the space behind the waterfall will be wide enough for a pedestrian walkway? Is her assurance true or false? (hint: a stream of water is subject to the same gravitational forces as any other object!) O True O False
