Question

name: hs physics unit 1 summative assessment task pole vaulting is an olympic track and field sport that requires great force, speed, and strength. the event starts with a 40.0 m sprint, then the jumper plants a pole in the ground and uses it to propel themselves up into the air. remarkably, the world record for the highest pole vault jump is just over 20 ft high, or 6.17 meters. this is taller than some houses! to help build her up to that olympic level, chloe is looking for your help to analyze her training plan and figure out, \whats the best way to increase my pole vault height to beat my competition?\ part 1: sprint races of past athletes one of the most important parts of a pole vaulters technique is the initial sprint down the runway. chloe has decided to focus on improving her sprint to maximize her velocity before she plants the pole on the ground. chloes coach, coach jackson, has given her three possible training plans (a, b, or c) to do during her off - season. in the first part of this task, you will evaluate which of the three training plans worked best for the past athletes. after his past athletes had completed the three different training plans, coach jackson had them run a sprint race against one another and used motion tracking technology to record data on their sprint performance running down the 40 m runway. graphs of the changes in distance, velocity, and acceleration over time for the three athletes are shown below. 1. use the space next to the graph to analyze each graph for patterns among the average data from the three different training plans. explain the patterns you see in the graph and how it helps you understand the training plans. distances over time for training plans - training plan a - - - training plan b ··· training plan c

Explanation:

Step1: Observe the graph

We see that Training Plan A starts with a slow - increase in distance, then has a steeper rise later. Training Plan B has a more linear increase in distance over time. Training Plan C starts with a relatively fast increase and then levels off a bit towards the end.

Step2: Analyze the implications

For Training Plan A, athletes may start slow but gain speed over the sprint. Plan B indicates a consistent speed throughout the sprint. Plan C shows a fast start but may not maintain the high - speed increase.

Answer:

Training Plan A has an initially slow but accelerating pattern. Training Plan B has a linear, consistent pattern. Training Plan C has a fast - start but slightly decelerating pattern towards the end. This helps in understanding the different speed - building characteristics of each training plan for the 40 m sprint in pole - vaulting.
