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 b. Determine the velocity of the water in the river relative to the ground. c. How far downstream will Olaf drift?" d. Determine the velocity of the person relative to the water (with direction) e. Determine the velocity of the person relative to the ground (with direction).

Two students perform an experiment with a train and a ball. Michelles rides on a fltcar pulled at 7.85 m/s by a train on a straight, horizontal track; Gary stands at rest on the ground near the tracks. When michelle throws the ball with an initial angle of 57° above horizontal, from her point of view, Gary sees the ball rise straight up and back down above a fixed point on the ground. A. Did michelle throw the ball toward the front of the train or toward the rear of the train? Explain b. What was the initial speed of Michelle’s throw? c. What was the initial speed of the ball as seen by Gary?

For A,B,and C
