A boat begins on the east side of a river and heads straight WEST across the river with a speed of 2.1 ft/s (relative to the water). The river water flows SOUTH at a speed of 3.6 ft/s (relative to the shore). The resultant velocity of the boat (relative to the shore) is approximately ft/s at degrees (CCW from east). Enter the two answers in their respective order.

Question 12

Devon tried to comfort Kayla after she tripped on the stage during the awards assembly. "It was nothing," he reassured her. "People barely noticed." His words didn't help. Kayla replayed the inelegant scene in her mind. As she had walked across the stage, she had felt her heel wobble slightly, sending her swaying back and forth. Then her foot had given out completely, and the auditorium had echoed as she hit the ground. After a few seconds, giggles from the audience had broken the silence. Kayla had been mortified, and her face had remained flushed as she grabbed her award and ran back to her chair. "I'm dying of embarrassment," she whispered in Devor's ear. "My life is ruined." Which statement best interprets the use of hyperbole in the passage?

By saying that the fall was 'nothing: Devon uses hyperbole to show that embarrassment is foolish.
By saying that the fall was 'nothing:' Devon uses hyperbole to show that Kayla is being too sensitive.
By saying that she is "dying," Kayla uses hyperbole to show how embarrassed she is.
By saying that she is 'dying; Kayla uses hyperbole to show that she was seriously injured by the fall.

Draw FBDs for the object rolling down the ramp (without slipping) and for the object while in the air. NOTE: Make sure your force vector arrows start exactly from where they act. There are three forces acting on the object as it rolls down the ramp. Which one causes a torque? Explain why the other two do NOT cause a torque. Which way does the net torque point? Explain the rotational motion down the ramp. Why is the net torque
