a) Brynn, who is standing on a balcony, is surprised by a pigeon and throws a flowerpot up in the air at 2.1 m/s. It takes 3.0 s for the flowerpot to smash to the ground. The flowerpot experiences acceleration due to gravity of 9.81 m/s [down]. Determine how high Brynn's balcony is from the ground, and how fast the flowerpot was moving just before it smashed to the ground. b) A water balloon is fired at 34.0 m/s from a water cannon, which is aimed at an angle of 18 above the ground. The centre of the cannon's target (which has a radius of 1.0 m) is painted on the asphalt 42.0 m away from the water cannon. Will the balloon hit the target? Justify your response with calculations that indicate where the water balloon will land and make one suggestion about how to adjust the water cannon so that the water balloon will hit the target. c) How can the fan on the airboat be used to change the direction the boat is travelling in? How can it be used to increase or decrease the speed of the boat? d) If the boat is going upstream against a current that has a force of 250 N against the motion of the boat, find the acceleration of the boat if there is a forward force of 360 N from the fan. (Note that the mass of the boat is 220 kg.) a) Brynn, who is standing on a balcony, is surprised by a pigeon and throws a flowerpot up in the air at 2.1 m/s.
