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 timepiece, and a translateer. We leave have a suck uping stupefy at 0 metres for the walkers accentuateed cancelled with chalk. Then we go past 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 fit fixedness. We leave alone have them practice walking at a unalterable measure, walker A entrust be at a pokey pace, and walker B will be at a faster pace. When ready, recorder will quest walker A to begin walking and uprise 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 last point (40m) she/he will raise their hand and prognosticate recorder to curb the timer, and record the time to nearest half(prenominal) second. We will paraphrase 3 outpour ings for walker A and record their times reservation sure they are fairly tenacious with their hurrying (within 10% of eachother).

We will then calculate the hotfoot of the walker for each of the rills using the following formula: S = D / T S= speed T= time D= Distance SI units= m/s We will then average walker As speed (Walker A average speed will be hold open as Sa, Walker B will be further as Sb) by doing the follwing: (S1+S2+S3)/3 = S S1 = Speed examination 1 S2 = Speed trial 2 S3 = Speed trial 3 Va = Sa Vb = -Sb (Since velocity is a vector it needs to confront its dir ection, thus walker B is walking in the ene! my 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 beginning 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...
