please answer d and e. -
Transcribed Image Text:3. Penny drops a leaf into the water which runs east downstream. She measures the distance
the leaf travels as 3.0 meters in 9.0 seconds. Penny then swims across the river, orienting
herself perpendicular to the water, and lets the river current carry her downstream. She
swims across the 57 m wide river in 47 seconds.
a. Sketch the overall vectors of the velocities of the person to the water, the water to the
ground and the person to the ground. Write the equation for the velocity of the person
relative to the ground with the appropriate subscripts

Expert Solution
Step 1
Dear student as per the guidelines I will be answering only parts d and e.
Given, Penny drops leaf into the water which runs east downstream.
The distance leaf travels in t=9.0s is s=3.0m
Penny then swims across orienting herself perpendicular to the water and letting the current carry her downstream.
she swims across a 57m wide river in 47s.
