A rescue plane is flying horizontally at a height of 97 m above ground. The pilot spots a survivor and releases an emergency kit with a parachute. The kit descends at a constant vertical acceleration of -6.63 m/s2 and the initial plane horizontal speed is 66.4 m/s. Assuming air resistance and wind are negligible, how far away from the survivor will the emergency kit hit the ground? 1.94km
254m
372m
359m

Aplane travels 1000 miles in 5 hours .what is the planes average speed?

Because air contracts as it cools, the air pressure inside a freezer is typically lower than on the outside. why do ice cubes inside a freezer tend to shrink over time? a. the ice dissolves oxygen from the air, forming a denser crystalline matrix.b. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds.c. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer.d. the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer.
