▼ Part A A walker and a runner are on a straight horizontal section of a track. In the reference frame of the Earth, the walker has an initial position XEwi = +5.0 m and the runner has an initial position XEri+15.0 m. Three seconds later, the walker has a position XEwf = +11 m and the runner has a position XErf +3.0 m. What is the runner's velocity in the reference frame of the walker, vwr? ► View Available Hint(s) O Vwr= -2.0 m/s O Vwr=-6.0 m/s O VW-18.0 m/s O Vwr= -4.0 m/s Review Submit

Steph Curry launches a basketball from a height of 2.36 m above the ground from the free throw line, which is 4.191 m to the left of the center of the hoop. The basketball makes it through the hoop, which is 3.048 meters above the ground, 1.13 seconds later. a.) what is the basketball's velocity when it leaves Steph's hands? b.) what is the basketball's velocity as it passes through the hoop?

Sheena can row a boat at 3.20 mi/h in still water. She needs to cross a river that is 1.20 mi wide with a current flowing at 1.80 mi/h. Not having her calculator ready, she guesses that to go straight across, she should head upstream at an angle of 25.0° from the direction straight across the river. a.)What is her speed with respect to the starting point on the bank? b.)How long does it take her to cross the river?

Part A and B on paper

A river flows due south with a speed of 2.8 m/s. A man steers a motorboat across the river; his velocity relative to the water is 4.9 m/s due east. The river is 600 mm wide. a-What is the magnitude of his velocity relative to the earth? b-What is the direction of his velocity relative to the earth? c-How much time is required to cross the river? d-How far south of his starting point will he reach the opposite bank?

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).

You have exactly 4 minutes 26 seconds to get to your next class on time and that classroom is 216 m east of where you are right now. First you run to your dorm room at an average velocity of 5.42 m/s to the south to pick up your calculator and your dorm room is 332 m south of where you were initially. What average velocity (magnitude only) do you now need to run from your dorm room to your classroom to arrive exactly on time?   a. 1.49 m/s   b. 5.42 m/s   c. 1.93 m/s   d. 2.06 m/s

You are walking around your neighborhood and you see a child on top of a roof of a building kick a soccer ball. The soccer ball is kicked at 50° from the edge of the building with an initial velocity of 10 m/s and lands 20 meters away from the wall of the building. How long was the ball in the air?
