Dennis, a senior in high school, is preparing for the greatest food fight prank of all time. He plans to launch watermelons from his homemade melon cannon machine towards the enemy food fighters standing on the rooftop lunch area. The enemies are 10 meters from the edge of the 7-meter-high balcony. Dennis plans to hide in some bushes away from the building to fire his cannon. The cannon fires at 22.0 m/s & must be angled 40° above ground to clear the bushes. a. How far from the base of the building should Dennis place the cannon? b. The teachers' lounge window is 14 above the ground. Will they be able to see the watermelons pass by their window (assume they are looking horizontally? 40°

Calvin is standing on the roof of a 6.50 m tall house. His tiger Hobbes is on the ground, some distance away from the house. Calvin is throwing water balloons at Hobbes: Calvin is throwing the water balloons with speed VO at an angle of 0 below the horizontal. On his first try, Calvin hits Hobbes with the water balloon! Hobbes is 3.02 m horizontally from the base of the building and it takes 1.04 s for the balloon to hit him. Coordinate system: positive x points to the right and positive y points up.
7. A force F, of magnitude 6.00 units acts on an object at the ori- gin in a direction 0 = 30.0° above the positive x axis (Fig. P3.7). A second force F, of magnitude 5.00 units acts on the object in the direction of the positive y axis. Find graphically the magni- tude and direction of the resultant Figure P3.7 force F, + F.
Use the component method to add the vectors A and B shown in Figure P3.9. Both vectors have mag- nitudes of 3.00 m and vector A makes an angle of 0 = 30.0° with the x axis. Express the resultant Á + B in unit-vector notation.

I need help on this problem: A pipe discharges storm water into a creek. Water flows horizontally out of the pipe at 1.9m/s, and the end of the pipe is 3.5m above the creek. How far out from the end of the pipe is the point where the stream of water meets the creek? Express your answer with the appropriate units.

Question: Diego is getting hungry and acting like a typical saber-toothed tiger. He visualizes Sid as a hunk of meat and begins to chase him frantically around the ground. First, Sid darts 50.0 meters at 35.0° NoW and then turns abruptly and races 40.0 m S. If Manny ran from where they were originally standing to where Sid ended up, how far and in what direction would Manny have to run to break up the fight? Use the triangle method to solve this. Should you use the component method, I will award zero points. I know the answer I just don’t know how to get it. Answer: 42.5 m @ 15.5° SoW Thanks!!
You are on the Pirates of the Caribbean attraction in the Magic Kingdom at Disney World. Your boat rides through a pirate battle, in which cannons on a ship and in a fort are firing at each other. While you are aware that the splashes in the water do not represent actual cannonballs, you begin to wonder about such battles in the days of the pirates. Suppose the fort and the ship are separated by 75.0 m. You see that the cannons in the fort are aimed so that their cannonballs would be fired horizontally from a height of 7.00 m above the water. (a) You wonder at what speed they must be fired in order to hit the ship before falling in the water. (b) Then, you think about the sludge that must build up inside the barrel of a cannon. This sludge should slow down the cannonballs. A question occurs in your mind: if the cannonballs can be fired at only 50.0% of the speed found earlier,is it possible to fire them upward at some angle to the horizontal so that they would reach the ship?
Mr. Brown takes a walk in the park. He first travels 600. m NW and then turns and walks 800. m @ 20.0° WoS. What is his overall displacement of his walk? Use the triangle method to solve this. Should you use the component method, I will award zero points. I know the answer, I just don’t know how to get it. Answer: 771 m @ 25.1° SoW Thanks!!
