Consider a polar coordinate system with the origin at O and r and measured as shown. Draw the radial and transverse unit vectors. 2. Project the velocity of the horse into the radial and transverse directions and show a diagram with the velocity vector and its components. 3. What is + and eat this instant? 4. From the perspective of the bale, what is the direction of the relative velocity of the horse (up/down/left/right/diagonal etc.). Draw vectorially the relative velocity of the horse with respect to the bale and include any relevant angles. 5. Will the magnitude of the relative velocity be equal to, greater than or lesser than 12ft/s?

The position of the EOAT (gripper hand) of the SCARA Robot in Robotics Factory in BGSU can be expressed by cylindrical coordinate system. Mechatronics student wrote a code that moves the EOAT from position P1 into position P2 at constant angular velocity of 2rad/s. The path generated between these two points, measured from base of the robot follow radial path r = cos m. Calculate the velocity magnitude of EOAT at 0 = 30°. A) 1 m/s B) 2 m/s C)2cos30 m/s D) None of the above.
I would like to know the answer to the questions and how you managed to obtain them. As shown on the coordinate system, points A and B have the following distances from the origin: xA = 3.10 ft , zA= 2.30 ft , xB = 2.80 ft , yB = 1.40 ft , and zB= 1.60 ft. 1) For the two points A and B, what are the i, j, k components of the position vector that starts at A and ends at B?
