- At what angle should an athlete throw a javeline for maximum range?Question 20 of 20 < A Water Balloon Battle. You are launching water balloons at a rival team using a large slingshot. The other team is set up on the opposite side of a flat-topped building that is 30.0 ft tall and 50.0 ft wide. Your reconnaissance team has reported that the opposition is set up 10.0 m from the wall of the building. Your balloon launcher is calibrated for launch speeds that can reach as high as 100 mph at angles between 0 and 85.0° from the horizontal. Since a direct shot is not possible (the opposing team is on the opposite side of the building), you plan to splash the other team by making a balloon explode on the ground near them. If your launcher is located 55.0 m from the building (opposite side as the opposing team), what should your launch velocity be ((a) magnitude and (b) direction) to land a balloon 5.0 meters beyond the opposing team with maximum impact (i.e. maximum vertical speed)?

- 1.An archer aims at a target. (a) Should she aim the arrow directly at the target? Why or why not? Draw a simple diagram to support your explanation. (b) How should her angle of aim change depending on the distance to the target? (c) Suppose the archer's arrow is 1.2m above the ground, the bull's eye is 43m away and at a height of 1.8m, and she can shoot the arrow at an initial speed of 28m/s. It is a calm day with no wind so we ignore air resistance. At what angle should she aim her arrow to hit the bull's eye? Not incompletewhat is the maximum height of a bullet shot from a gun at 150 m/s at a 5.0 degree angle?3.13 A car comes to a bridge during a storm and finds the bridge washed out. The driver must get to the other side, so he decides to try leaping it with his car. The side the car is on is 20.6 mm above the river, whereas the opposite side is a mere 1.9 mm above the river. The river itself is a raging torrent 60.0 mm wide. 1.How fast should the car be traveling just as it leaves the cliff in order to just clear the river and land safely on the opposite side?2.What is the speed of the car just before it lands safely on the other side?
