In this calculus proble, a machine design has endpoints of a moveable rod of length 1 meter have coordinates (x,0) and (0,y). The position of the end on the x-axis has a formula given at t is the time in seconds. the formula and this 3 part question is listed ona a separate attachment.

I need these three parts answered, if you are unable to answer all three parts please leave it for another tutor to answer, thank you.

Required information A model of a person's arm is used for ergonomics studies. Distances are rAB = 30 cm, BC = 28 cm, and rCD = 19 cm. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. y D C25° 30 Determine the position vector TAD and its magnitude rAD· The position vector TAD 1i)cm and the magnitude rAD is cm.

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
