Homework Answers
given that
weight of the gymnast W = mg = 700 N
angle with the vertical = 60 degrees
from the figure
2Tcos(60) = 700 N
T = 700/(2*cos(60))
T = 700 N

Before practicing a routine on the rings, a 64.8 kg gymnast hangs motionless, with one hand grasping each ring and the feet touching the ground. Both arms make an angle of 24.4° with the vertical. If the force exerted by the rings along each arm has a magnitude of 305 N, what is the magnitude of the force exerted by the floor on the feet?

After rounding second base, a baseball player with a mass of 77 kg slides into third base. The coefficient of kinetic friction between the player and the ground is 0.42. What is the magnitude of the friction force acting on the player? If it takes 1.3 s for the player to come to a rest at the base, what was his velocity when he initiated his slide? Suppose you are pulling a 4.2-kg block across a rough, horizontal surface with...

A 75 kg person is crouching with his weight evenly distributed on both tiptoes. The forces on the skelet part of foot are shown in Fig. 12.9 below. In this position, the Achilles tendon experiences a force F., making an angle a = 59.2° with the horizontal. The tendon acts on the ankle a horizontal distance d= 9.66 cm from the point where foot touches the floor. The tibia acts on the foot with magnitude | F and makes an...

1. Three children are riding on the edge of a merry‑go‑round that has a mass of 105 kg and a radius of 1.80 m. The merry‑go‑round is spinning at 22.0 rpm. The children have masses of 22.0, 28.0, and 33.0 kg. If the 28.0 kg child moves to the center of the merry‑go‑round, what is the new angular velocity in revolutions per minute? Ignore friction, and assume that the merry‑go‑round can be treated as a solid disk and the children...

As shown in (Figure 1), a car engine with weight to hangs from a chain that is linked at point to two other chains, one fastened to the ceiling and the other to the wall. Find the tension in each of the three chains, assuming that is given and...

1. John (who is 95 kg) drives his car over an absurdly large half-circle speedbump with a radius of 5 meters. Given that his normal weight is 930 N and his apparent weight at the top of the speed-bump was 246 N, how fast did he drive over the speed bump? 2. When working in circular motion problems, what do we define as always being the positive direction? 3. When in circular motion, the net force points in what direction?...
