The woman at C stands near the edge of a pier and pulls the rope horizontally at a constant speed of 6 ft/s. Find an equation for the speed of the boat as a function of the rope length AB as AB goes from 50 ft to 15 feet. Does the boat speed up, slow down, or move at a constant speed as it approaches the pier? A sketch or plot may be useful. 8 ft 6 ft/s B

▼ 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?
