A ball is thrown eastward into the air from the origin (in thedirection of the positive x-axis). The initial velocityis
50 i + 80 k,
with speed measured in feet per second. The spin of the ballresults in a southward acceleration of 8 ft/s2, so theacceleration vector is a = ?8 j ?32 k. Where does the ball land? (Round youranswers 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 toone decimal place.)
___________ ft/s
