The angular excursion during the deceleration period c. The linear distance moved during this phase BME 465 Homework 6 6. The kicking part of a football punt takes 0.25s, the hip flexion excursion is 89o, knee extension excursions in 100o, assuming the thigh is 0.7m and shank (calf) is 0.68m. Calculate the tangential velocity of the foot during this movement? (10 points) 7. A discus thrower rotates through the last 50° of a turn in 0.12 seconds. The distance from his shoulder to his hand is 1.00 m and the distance from the axis of rotation to the center of the discus is 1.17 m. Calculate the average linear velocity of the discus. (5points) 8. A bike wheel makes 1.5 revolutions with an average angular velocity of 18 rad/s. You place your hand on the wheel to slow it down at a rate of 500°/s2. How much angular distance is traveled before the wheel comes to a stop? (5points) 9. A merry-go-round has a radius of 3.0 m. Child A runs around, pushing it with a velocity of 4.0 m/s. It takes Child B 4.71 seconds to make one revolution when he pushes the merry-go-round. Which child pushes it faster? (A/B/Equal/Not enough information). (5points) Note: To get credit you must show your work or tell me what other piece of information you would need to solve the problem. 10. Consider someone whose forearm is 26 cm long and their upper arm is 38 cm long. Based on a frame of motion capture data where the shoulder joint center is considered our origin and the elbow joint center is located at (-25.4, -28.23) cm and the wrist joint center is located at (-0.97, -37.12) cm, calculate: (10 points) The absolute angle that the forearm and upper arm segments make with the horizontal The absolute angle that the forearm and upper arm segments make with the vertical The elbow joint angle Get a 10 % discount on an order above $ 100 Use the following coupon code : NURSING10
