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)?

25. A student wants to perform an experiment where they have to measure the time interval for a ball bearing rolling down a slope (as with your first practical), in order to determine the acceleration on the ball-bearing. They take 1 measurement for every distance (they move the end of the measuring equipment 10 cm further way every time), and then they plot a graph. This graph comes out with very scattered values that do not form a straight line at all. What could be the reason for this? Choose all correct answers. A. They should have taken more than one measurement at every distance. B. The stopping wires might have malfunctioned sometimes, so they should have made sure that the stopping wires only touched the metal when the ball bearing rolled over it. C. The graph is fine with only one value measured per distance. It is the acceleration that was not consistent. Nothing needs to be changed. D. The graph axes need to be adjusted to make the data show a straight line.

Posted below is a picture of a data table and a diagram of an experiment. In the experiment you rolled a marble down a ruler ramp off the end of a coffee table to observe projectiles and conservation of energy. You do 3 trials for each initial height. Each height is measured in meters. h= initial height of marble off of table Y= height of table off floor X= horizontal distance marble goes from edge of table to where it strikes the floor a) use the table to find information you need to solve for theoretical range and % of error in measured range.

Hi. I am trying to practice this problem using a checker online, but everytime I recalculate my answer it always says it's incorrect. So far I have calculated and tried to input the following values: 1 hp, 1.01 hp, and 0.8 hp but it always keeps saying they are incorrect. Am I missing a sign change? (Should the answer be negative?) Or am I solving this incorrectly and getting the wrong value each time? Please help show me the correct steps on how to get the correct answer as I am trying to learn this process. Thank you!
