A woman walks at a constant rate for 10 seconds. For the next 5 seconds the woman speeds up to a run. After running at a steady rate for 5 more seconds, the woman stops for 5 seconds. It then takes the woman 5 seconds to run back to where she started. Graph the position of the woman as a function of time. Be sure to label your graph including time intervals.© BrainMass Inc. brainmass.com October 25, 2018, 4:45 am ad1c9bdddf
Please refer to the attachment for the fully formatted solution and the accompanying graphical depiction of the response.
Woman's motion can be described in the following stages:
1. 0 < t < 10 sec: Constant speed (say u). The displacement with respect to the origin changes as per the equation: x = ut ........ (1)
[Note: We take the woman's position at t = 0 as the origin i.e. x = 0]
Equation (1) is that of a ...
This solution shows how to create a graph showing a woman's walking trajectory as a function of time, given her movement pattern and the time frame.
Two cars lost in a blinding snowstorm are traveling across a large field, each thinking they are on the road, as shown in the figure on the left. They collide. If the distance x is 124 meters and the red car is travelling at 12.7 mph, how fast to the nearest hundredth of a mph was the blue car travelling? 10.37 mph? How do I figure out how much time passes before the cars collide to the nearest tenth of a second?View Full Posting Details
