Question

A ball is thrown eastward into the air from the origin (in the direction of the positive x-axis). The initial velocity is

50 i + 80 k,

with speed measured in feet per second. The spin of the ball results in a southward acceleration of 8 ft/s², so the acceleration vector is a = −8 j − 32 k. Where does the ball land? (Round your answers to one decimal place.)

_______________ft from the origin at an angle of ________________ ° from the eastern direction toward the south.

With what speed does the ball hit the ground? (Round your answer to one decimal place.)
___________ ft/s
