Ballast Dropped from a Balloon A ballast is dropped from a stationary hotiair balloon that is hovering at an altitude of 370 ft. The velocity of the ballast after .t sec is 73% ttfsec. (3] Find the height Mt} (in feet} of the ballast from the ground at time t. ant': h'[fj = 732? and hm) = 370. hm = (b) when will the ballast strike the ground? (Round your answer to two decimal places.) (c) Find the velocity of the ballast when it hits the ground {Round your answer to two decimal places.) Em
