- At a particular instant, a hot air balloon is 100 m in the air and descending at a constant speed of 2.0 m/s. At this exact instant, a girl throws a ball horizontally, relative to herself, with an initial speed of 35 m/s. When she lands, where will she find the ball? Ignore air resistance.A sandbag is dropped from a balloon which is ascending vertically at a constant speed of 6 m/s. If the bag is released with the same upward velocity of 6 m/s when t = 0 s and hits the ground when t = 8 s, determine the speed of the bag as it hits the ground and the altitude of the balloon at this instant.A ball is kicked at ground level with an initial velocity of 19.5 m/s in the horizontal direction and 12.5 m/s in the vertical direction.At what speed in m/s does the ball hit the ground?For how long does the ball remain in the air in seconds?What is the maximum height reached by the ball in meters?
