v Part 2: Make a Prediction The first video in the set below shows a collision between a blowdart and a low-friction cart. Watch the video to see the entire collision Our goal is to apply the law of conservation of momentum to predict the outcome of a collision Tke this one and then to see it our prediction is correct Click Charge on the video player and select trial 9. All your answers will be based on mensurements made from trial 9. Ocm 10 20 30
Ocm 10 20 30 dart mass: 28.19 cart mass: 300,8 g 8.1500 sec Frame 36 240 fps pivot TRIAL 9 Change a
o 1. Let's start by measuring the distance the dart moves in the last five frames before it collides with the foam block on the cart: . Select trial by clicking Change at the bottom of the video . Click the tools icon and click the stopwatch and ruler tools • Position the ruler so you can measure the position of the dart as it moves from the fauncher to the cart • Measure the distance the dart moves in the last five video frames before the dart colides with the cart Enter your answer below. 10 cm Sutmint Awet w nilimited submissions remaining Score: 1/1 Comments: This is nearly correct but not close enough to produce an accurate prediction. You may want to refine your measurement before continuing. Here are some tips for making this measurement • advance the video until the last frame just before the dart hits the foam block on the cart use the arrow keys on your keyboard or the frame-back button on the video player to go back five more frames • place the Ocm of the ruler at the tip of the dart • advance five frames • measure the location of the tip of the dart Here's how it may look: 0.0833
1 2. Calculate the velocity of the dart during this time, in meters per second m/s Submit Answer * unlimited submissions remaining Heads Up! You need to submit this answer for it to save and be graded Score Comments: 0/1 To find the velocity, you'll need to determine how much time lapses during five frames. You can use the stopwatch to measure time. Also, notice the video is recorded at 240 frames per second, so each frame is 1/240 seconds. How much time clases during five frames? 3.
