3. Suppose you are 3.3 km away from rifle range where someone is

practicing shooting. How long would it take you to hear the sound of a

shot fired by him? (Speed of sound 344m/s) please please answer as soon as possible otherwise i am dead dead by my teacher

If a stone with an original velocity of 0 is falling from a ledgeand takes 8 seconds to hoybthe ground whays the final velocity of the stone

If element x has 99 protons how many electrons does it have

Aspring is used to stop a 50-kg package which is moving down a 20º incline. the spring has a constant k = 30 kn/m and is held by cables so that it is initially compressed 50 mm. knowing that the velocity of the package is 2 m/s when it is 8 m from the spring and neglecting friction, determine the maximum additional deformation of the spring in bringing the package to rest.
