Unlike most of the other muscles in our bodies, the masseter muscle in the jaw, as illustrated in the figure, is attachedrelatively far from the joint, enabling very large forces to be exerted by the back teeth. This is shown in the figure below,where a person is biting down on a bullet placed between the back teeth. (FM= 200 N and r. = 3.7 cm.)M= 2.9 cmMassetermuscleгeaction(a) Using the information in the figure, calculate the magnitude of the force exerted by the teeth on the bullet.(b) Calculate magnitude of the force on the joint.

A stubborn dog is being walked on a leash by its owner. At one point, the dog encounters an interesting scent at some spot on the ground and wants to explore it in detail, but the owner gets impatient and pulls on the leash with force F ⃗ = (98.0i ^ + 132.0j ^ + 32.0k ^ )N along the leash. (a) What is the magnitude of the pulling force? (b) What angle does the leash make with the vertical?
A loaded penguin sled weighing 68.0 N rests on a plane inclined at angle θ = 18.0° to the horizontal (see the figure). Between the sled and the plane, the coefficient of static friction is 0.290, and the coefficient of kinetic friction is 0.150. (a) What is the minimum magnitude of the force F→, parallel to the plane, that will prevent the sled from slipping down the plane? (b) What is the minimum magnitude F that will start the sled moving up the plane? (c) What value of F is required to move the sled up the plane at constant velocity?
A metal weight of mass 15 kg rests on a smooth (that is, frictionless) icy slope that makes an angle of 25° with the horizontal.

A person is pushing a wheelbarrow along a ramp that makes an angle a = 23.0° with the horizontal. The wheelbarrow and load have a combined mass of m = 28.85 kg with the center of mass at the midpoint of the length L. What is the Fx magnitude of the net force Fnet that the person must apply in order to push the wheelbarrow up the ramp at a constant velocity, while keeping the wheelbarrow in a level, horizontal orientation? Assume that the radius of the wheel is small enough to ignore. Use g = 9.81 m/s². total force: N
A bull shark has a reduced weight (or “submerged weight” = W - B) of 4Nin seawater and 12N in freshwater, i.e., as found in rivers (bull sharks have been known to swim into rivers from the ocean – including the Mississippi river!). How much more lift force needs to be generated when transitioning from sea to freshwater? Assuming that CL stays the same, calculate how much faster the shark has to go in order to swim horizontally in freshwater (i.e., relative to the swim speed in saltwater)?
Body U with mass 5m is stacked on the top body W withmass m, and released. The bodies are in contact along thefrictionless interface at 45 to the vertical. The body U isin contact with the frictionless vertical wall. Body W lieson the floor with coefficient of friction u. Relevantdimensions are shown in the figure. Express the results interms of given quantities: m, g, h and u. Body U must stay in contact with the wall. Using the equations of motion for the two bodies compute the accelerations during the motion while in contact.
A 70 kg bicyclist is riding her 15 kg bicycle downhill on a road with a slope of 80without pedaling or braking. The bicyclist has a frontal area of 0.45 m2and a dragcoefficient of 1.1 in the upright position, and a frontal area of 0.4 m2and a dragcoefficient of 0.9 in a racing position. If the downhill speed of the bicyclist(terminal velocity) can be determined when the total force acting on the “body” inthe direction of movement is equal to zero, determine the percentage of downspeed that she can be increased when she is in a racing position. Air temperatureis 150C and disregarding the rolling resistance and friction at the bearing.
