There are two forces on the 1.19 kg box in the overhead view of the figure but only one is shown. For F1 = 15.7 N, a = 14.7 m/s2, and θ = 34.1°, find the second force (a) in unit-vector notation and as (b) a magnitude and (c) a direction. (State the direction as a negative angle measured from the +x direction.)
A particle, which remains at rest, is acted on by three forces: F, G & H. The force F has a magnitude of 45N and is directed to the left and down making an angle of 45 degrees with the vertical. The force G is directed horizontally right and H is directed to the right and up making an angle of 30 degrees with the vertical. Find the magnitude of the vectors G and H to 1 d.p.
A hiker who has broken his forearm rigs a temporary sling using a cordstretching from his shoulder to his hand. The cord holds the forearmlevel and makes an angle of 40.0° with the horizontal where it attachesto the hand. Considering the forearm and hand to be uniform, with atotal mass of 1.30 kg and a length of 0.300 m, find (a) the tension inthe cord and (b) the horizontal and vertical components of the force, f>,exerted by the humerus (the bone of the upper arm) on the radius andulna (the bones of the forearm).
A persons head is bent over a book. The head weighs P=37.2 N and is supported by the muscle force Fm exerted by the neck extensor muscles and by the contact force Fc excerted at the atlantooccipital joint. Given that the magnitude of Fm is 60.0 N and is directed 35.0 degree below the horizontal. Find the direction of the contact force Fc. If the direction is below the horizontal, enter a negative value.

The distance between two telephone poles is d = 54.0 m. When a 1.20 kg bird lands on the telephone wire midway between the poles, the wire sags h = 0.206 m. How much tension (in N) does the bird produce in the wire? Ignore the weight of the wire
A 1.50×103 kg car, whose front is facing to the right (towards +x-axis) and whose engine is turned off and in neutral, is held at rest on a frictionless ramp using a cable whose one end is attached to the car’s front at an angle 27.0◦ with respect to the ramp’s surface. The other end of the cable is attached to a wall perpendicular to the horizontal and the ramp is raised 30.0◦ above the horizontal. b. Find the tension on the cable.

A 4.00kg block rests on a 30.0o incline.if the coefficient of static friction between the block ad the incline is 0.700, what magnitude horizontal force F must act on the block to start it moving up the incline?
In about 1915, Henry Sincosky of Philadelphia suspended himself from a rafter by gripping the rafter with the thumb of each hand on one side and the fingers on the opposite side. Sincosky’s mass was 79 kg. If the coefficient of static friction between hand and rafter was 0.70, what was the least magnitude of the normal force on the rafter from each thumb or opposite fingers? (After suspending himself, Sincosky chinned himself on the rafter and then moved hand-over-hand along the rafter. If you do not think Sincosky’s grip was remarkable, try to repeat his stunt.)
