PostLab Questions: Stopping distance is the total distance traveled by a car before it comes to a complete stop. It is used to describe the distance traveled by a driver who is traveling at various speeds who reacts to a stopping stimulus.

Calculate the stopping distance for the case of the 30kmlh initial speed, and the reaction time, and fill in the rst rout.r of the table above. 2. Calculate the acceleration involved for the data given in first row of the table above. Show work in the space below for credit. 3. Assume the same acceleration for all the bra king distances for the other speeds. Calculate the reaction times for all the other speeds listed in the table. Show all work for credit. 5. Ima Rllla Saari is cruising at 28.0 mls down Lake Avenue and through the forest preserve. She notices a deer jump into the road at a location 62.0 m in front of her. Ima first reacts to the event, then slams on her brakes and decelerates at -8.10 mfsz, and ultimately stops 3 centimeter in front of the deer which had frozen out of fear. What is Ima's reaction time? Show all work for credit. Purpose: To calculate your reaction time. Procedure: 1. Hold out your hand flat and have yOur lab partner hold a ruler above your hand, so that the Dem mark on the ruler is on the top of your hand, as shown in the diagram below. 2. Without warning, your lab partner drops the ruler, and you will try and catch it If": qr Your as soon 35 you can. h'\" \"In le 3. Calculate your reaction time from the displacement of the ruler. 0 cu m ar 4. Perform four trials and then find the average distance the ruler dropped. Data: Trial 1: Displacement ofruler: cm = m Trial 2: Displacement of ruler: cm = m Trial 3: Displacement ofruler: cm = m Trial4: Displacement ofruler: cm = m Average displacement of ruler: cm H 3 Calculation: Show calculation oft: Analysis: Use a computer that can plavthe following flash game.
