A gymnast swings on the high bar as shown in the figure. Starting from rest directly over the bar, he swings around the bar while keeping his arms and legs outstretched. Treating the gymnast as though his entire mass were concentrated at a point y=0.87 m from the bar, determine his speed as he passes under the bar at position A. Note that you do not need know his mass to solve this problem.
It is asking for the units in m/s
A meter stick is used as a physical pendulum as shown. Determine the angular acceleration of the meter stick when q = 35.00 if the pivot is at the 20.0 cm position.

- Figure P10.16 shows the drive train of a bicycle that has wheels 67.3 cm in diameter and pedal cranks 17.5 cm long. The cyclist pedals at a steady cadence of 76.0 rev/min. The chain engages with a front sprocket 15.2 cm in diameter and a rear sprocket 7.00 cm in diameter. Calculate (a) the speed of a link of the chain relative to the bicycle frame, (b) the angular speed of the bicycle wheels, and (c) the speed of the bicycle relative to the road. (d) What pieces of data, if any, are not necessary for the calculations? Figure P10.16arrow_forwardA nylon siring has mass 5.50 g and length L = 86.0 cm. The lower end is tied to the floor, and the upper end is tied to a small set of wheels through a slot in a track on which the wheels move (Fig. P18.76). The wheels have a mass that is negligible compared with that of the siring, and they roll without friction on the track so that the upper end of the string is essentially free.

In this image, the two front legs are rotating in opposite directions from our point of view one clockwise and one counter-clockwise around their respective shoulder joints. These images and those like them helped scientists understand the physics of gross-motor-motion for living things. In your first post, discuss the functional morphology or gait of a person or animal species as it relates to your data and observations. For example: How does a person change the moment of inertia of their arm when beginning to run as compared when they are walking? If you look at a picture of a running horse like the one shown below, can you tell which legs are rotating so that the foot moves toward the front of the horse and which are rotating in the opposite direction?
