Amortar is like a small cannon that launches shells at steep

angles. a mortar crew is positioned near the top of a steep

hill. enemy forces are charging up the hill and it is

necessary for the crew to spring into action. angling the

mortar at an angle of 0 = 49.0° (as shown), the crew fires

the shell at a muzzle velocity of 182 ft/s.

how far d down the hill does the shell strike if the hill

subtends an angle 0 = 38.0° from the horizontal? ignore

air friction.

An object is located 30.0 cm from a concave mirror. the focal length is 15.0 c,. what is the image distance? a. 30.0 cm b. -10 cm c. 10.0 cm d. -30.0 cm

Apossible explanation for a set of facts that can be tested by further investigation is called

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?
