A package is dropped from a helicopter traveling at 21 m/s (horizontally) at an altitude of 210 m but the parachute attached to the package fails to open. What is the speed of the package just before it lands

Organelles are 1. responsible for producing power for the cell 2. tiny structures in the cell that carry out the cell's activities 3. responsible for digestion in the cell 4. found outside of the membrane

Avehicle accelerates from 0 to 30 m/s in 10 seconds on a straight road

Two masses are connected by a rope that hangs over a pulley as shown below. the pulley is a uniform cylinder of radius 푅=0.381meters and mass 푀=3.1푘푔. initially 푚"is on the ground and 푚#rests 2.5 meters above the ground. if the system is released, use conservation of energy to determine the speed of 푚#just before it strikes the ground. assume the pulley bearing is frictionless.
