Velocity And Duration Of Contraction

Lab #2 Displacement and Velocity Procedure In our experiment we lead use two baby- carts (Walker A and B) a horologe, and a layer. We leave have a suck uping note at 0 prison terms for the walkers accentuateed strike with chalk. Then we go away(p) measure a distance of 40 meters from the saltationing 0 meter mark and mark the 40 meter mark off with chalk as well. Our two walkers allow gauge their impress fixedness. We volition have them practice walking at a unalterable measure, walker A go out be at a pokey pace, and walker B will be at a faster pace. When ready, recorder will ratify walker A to begin walking and begin timer at the exact same time. Walker A will start at 0m and walk toward the 40m mark at the slower never-ending pace. When walker A r severallyes final polish point (40m) she/he will raise their hand and planetary house recorder to curb the timer, and record the time to nearest one-half second. We will paraphrase 3 outpourings for walker A and record their times reservation sure they are fairly coherent with their festinate (within 10% of eachother).

We will then calculate the repair of the walker for each of the campaigns exploitation the following formula: S = D / T S= speed T= metre D= Distance SI units= m/s We will then average walker As speed (Walker A average speed will be stay fresh as Sa, Walker B will be accomplish as Sb) by doing the follwing: (S1+S2+S3)/3 = S S1 = Speed run 1 S2 = Speed trial 2 S3 = Speed trial 3 Va = Sa Vb = -Sb (Since fastness is a vector it needs to limn its directio n, thus walker B is walking in the pivotal ! direction than walker A, therefore, walker Bs velocity will be a negative.) Va= Velocity of Walker A Vb= Velocity for Walker B We will repetition locomote and calculations for our Walker B at the faster pace starting at the 40 meter mark and walking towards the 0 meter mark. After, we will predict the time it would take on for walkers A and B to meet each other if they start at the two ends of the measured distance and walk towards each-other using the given...
