Unformatted text preview: a. Locate and compute the coordinates of P (0), P (0.5), and P (1) in the picture. b. Compute the horizontal velocity ) ( t x ′ and vertical velocity ) ( t y ′ . What are the maximum (minimum) vertical and horizontal velocities? c. During the first trip of the object around the ellipse, find where the object is located when it has vertical velocity 3 ft/sec. d. During the first trip of the object around the ellipse, how much of the time will the horizontal velocity exceed 8 ft/sec? e. Plot the point )) 1 ( ) 1 ( ), 1 ( ) 1 ( ( ) 1 ( y y x x Q ′ + ′ + = and find the equation of a line through the points P (1) and Q (1). Draw this line in the picture. What can you say about this line? f. Plot the point )) 5 . ( ) 5 . ( ), 5 . ( ) 5 . ( ( ) 5 . ( y y x x Q ′ + ′ + = and find the equation of a line through the points P (0.5) and Q (0.5).
