Chapter 1, Problem 51GP
Muscle attachment. When muscles attach to cones, they usually do so by a series of tendons as shown in Figure 1.29. In the figure five tendons attach to the bone. The uppermost tendon pulls at 20.0° from the axis of the bore and each tendon is directed 10.0° from the one next to II. (a) If each tendon exerts a 2.75 N pull on the bone, use vector components to find the magnitude and direction of the resultant force or this bone due to al five tendons. Let the axis of the bone be the +x axis. (b) Draw a graphical sum to check your results from part(a).

An outfielder throws a baseball to his catcher in an attempt to throw out a runner at home plate. The ball bounces once before reaching the catcher. Assume the angle at which the bounced ball leaves the ground is the same as the angle at which the outfielder threw it as shown in the figure, but that the ball's speed after the bounce is one-half of what it was before the bounce.

(a) Assuming the ball is always thrown with the same initial speed, at what angle & should the fielder throw the ball to make it go the same distance D with one bounce (blue path) as a ball thrown upward at 35.0° with no bounce (green path)?
24
(b) Determine the ratio of the time interval for the one-bounce throw to the flight time for the no-bounce throw.
