Review conceptual example 15 before attempting this problem. two identical pellet guns are fired simultaneously from the edge of a cliff. these guns impart an initial speed of 42.6 m/s to each pellet. gun a is fired straight upward, with the pellet going up and then falling back down, eventually hitting the ground beneath the cliff. gun b is fired straight downward. in the absence of air resistance, how long after pellet b hits the ground does pellet a hit the ground?

Asimply means that over time there was some sort of change.

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?
