Two masses mA =9.3kg and mB=6.1kg are on inclines and are connected together by a string as shown in the figure. The angles theta subscript A=700 and theta subscript B = 360 . In the absence of the friction, the force F is required to pull the masses at a constant velocity up the fixed inclines. The force F is now removed. What is the magnitude of the acceleration of the two blocks? Take g =9.81 m/s2, and express your answer using two decimal places.
It is intended to remove a stake from the ground by means of two ropes, as shown in the figure. Knowing the magnitude and direction of the force exerted on one string, determine the magnitude and direction of the force P that must be exerted on the other string if the resultant of the two forces is to be a 40-lb vertical force.

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.
