You are watching a jet ski race. A racer speeds up from rest to 70 mph in just a few seconds, then continues at a constant speed. Part A Select the correct basic motion diagram of the jet ski, using images from the video, from 10 s before reaching top speed until 10 s afterward. ▸ View Available Hint(s) Os =70 mph Os 4=10s = 70 mph =10s x (m) 420 s (= 20s x (m) = 70 mph OS 4,= 10s =20s x (m) Submit Provide Feedback

Find the acceleration of the specified object. (Hint: Recall that if a variable is changing at a constant rate, its acceleration is zero.) A boat is pulled into a dock by means of a winch 16 feet above the deck of the boat (see figure). The winch pulls in rope at a rate of 7 feet per second. Find the acceleration of the boat when there is a total of 20 feet of rope out. (Round your answer to three decimal places.) ft/sec² Need Help? Read It Not drawn to scale
