Aball is thrown eastward into the air from the origin (in the direction of the positive x-axis). the initial velocity is 40 i + 32 k, with speed measured in feet per second. the spin of the ball results in a southward acceleration of 6 ft/s2, so the acceleration vector is a = −6 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
