Part 1 of 8- Conceptualice Think about what quantities the students must measure or calculate to make their goal of getting the ball into the canister. Of course, they will measure the horizontal and vertical distances from the launch point to the canister. After which, they need a plan. Which statement best describes a plan that will help them make their goal? Use the trial shot to find the muzzle speed, Once they know the muzzle speed, they will solve for the launch angle using the range equation, O use the trial shot to find the muzzie speed. Once they know the muzzle speed they will solve for the launch angle, taking into account the parabolic arc of the path. O The range equation cannot be used to aim the launcher at the canister because it doesn't take air resistance into account. The trial should be used to see how to compensate for air resistance, So, find the angle by taking the inverse-tangent of the ratio of the distance measurements. Once they know this angle, they use the range equation to predict how far the ball will travel. Then they set the launcher to that angle and measure how far it really travels. Next they must take into account the difference between the actual distance and the predicted distance when re-calculating the angle for the real trial. O The angle comes from taking the inverse-tangent of the ratio of the distance measurements. Once they know this angle, It is best to use the trial shot as practice so slight adjustments can be made to the real shot. O The angle should be set for 45° because that always gives the maximum range. Then they should use the trial run for practice to be sure they can smoothly release the trigger. The range equation can only be used if the ball lands at the same height from which it was launched. It won't work here because the canister is above the launch point.
