Some plants disperse their seeds when the fruit splits and contracts, propelling the seeds through the air. The trajectory of these seeds can be determined with a high-speed camera. In an experiment on one type of plant, seeds are projected at 20 cm above ground level with initial speeds between 2.3 m/s and 4.6 m/s. The launch angle is measured from the horizontal, with +90∘ corresponding to an initial velocity straight up and -90∘ straight down. If a seed is launched at an angle of 0∘ with the maximum initial speed, how far from the plant will it land? Ignore air resistance, and assume that the ground is flat. 20 cm 93 cm 2.2 m 4.6 m
