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 studyer. We leave have a suck uping go down at 0 verses for the walkers accentuateed by with chalk. Then we go remote 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 pass fixedness. We ordain have them practice walking at a unalterable measure, walker A pull up stakes be at a drawn-out pace, and walker B will be at a faster pace. When ready, recorder will presage walker A to begin walking and lead 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 destination point (40m) she/he will raise their hand and presage recorder to curb the timer, and record the time to nearest one-half second. We will paraphrase 3 outpourings for w alker A and record their times reservation sure they are fairly invariable with their hotfoot (within 10% of eachother).

We will then calculate the focal ratio of the walker for each of the tribulations utilize the following formula: S = D / T S= speed T= conviction D= Distance SI units= m/s We will then average walker As speed (Walker A average speed will be salve as Sa, Walker B will be economise as Sb) by doing the follwing: (S1+S2+S3)/3 = S S1 = Speed ravel 1 S2 = Speed trial 2 S3 = Speed trial 3 Va = Sa Vb = -Sb (Since pep pill is a vector it needs to pose its direc tion, thus walker B is walking in the polar! 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 step and calculations for our Walker B at the faster pace first 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...
