A man jumps out of a plane without a parachute. He eventually reaches a point where the force of gravity is equal and opposite to the force of air resistance (friction)? Which best describes his motion at this point. a
The man continues to descend, but with constant speed.
b
The man falls with a smaller but non-zero acceleration.
c
The man descends with slower and slower speed.
d
The man comes to a stop.
e
The acceleration of the man is now upward.

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?
