Assume the acceleration of the object is a(t] = 32 feet per second per second. (Neglect air resistance.) A balloon, rising vertically with a velocity of 16 feet per second, releases a sandbag at the instant when the balloon is 32 feet above the ground. {a} How many seconds after its release will the bag strike the ground? [Round your answer to two decimal places.) r=x {b} At what velocity will it strike the ground? (Round your answer to three decimal places.) v=_x we
