The helicopter view in the figure below shows two people pulling on a stubborn mule. (Take

F1 = 145 N and F2 = 75.0 N.

)

An illustration shows the helicopter view of a mule being pulled along a forked road in two directions by two men. An x y coordinate system is overlaid on the image, with the origin at the mule's nose, and the mule facing in the positive y-direction. The man on the right is pulling the mule toward the right-side forked road with a force F1. This force vector makes an angle of 60.0° with the horizontal drawn right in front of where the mule is standing. The man on the left is pulling the mule toward the left-side forked road with a force F2. This force vector makes an angle 75.0° with the horizontal.

(a) Find the single force that is equivalent to the two forces shown.

direction    


(b) Find the force a third person would have to exert on the mule to make the net force equal to zero.

A cook holds a 1.80-kg carton of milk at arm's length (see the figure below). What force FB must be exerted by the biceps muscle? (Ignore the weight of the forearm. Give the magnitude.) An arm is extending horizontally to the left with a cutout that shows muscles in the upper arm. A carton of milk is in the hand, and an arrow labeled vector Fg points directly downward. A point on the person's forearm lies a horizontal distance of...

The figure below shows a person fishing with a fishing rod that makes an angle of 20.0° above the horizontal. The distance from the person's hand to the tip of the rod is L = 2.04 m. A fish is on the line, and it pulls the line with a force of F = 121 N at an angle 37.0° below the horizontal. What is the magnitude of the torque (in N · m) exerted by the fish about an...

The figure below shows two masses m1 =8.6 kg and m2 =2.8 kg on a frictionless surface. As shown, a force F1 =23.6 N pushes on m1 from the left and a force F2 = - 14.9 N pushes on m2 from the right. Find the force that m1 exerts on m2. (Hint, make use of Newton's third law and find the acceleration of the entire system first).

Figure shows two industrial spies sliding an initially stationary 225 kg floor safe a displacement d of magnitude 9.5 m. The push F1 of spy 001 is 12 N at an angle of 40 degrees downward from the horizontal, the pull F2 of the spy 002 is 10 N at 50 degrees above the horizontal. The magnitudes and directions of these forces do not change as the safe moves, and the floor and safe make frictionless contact. (a) What is...

The diagram below shows a block of mass m=2.00kgm=2.00kg on a frictionless horizontal surface, as seen from above. Three forces of magnitudes F1=4.00NF1=4.00N, F2=6.00NF2=6.00N, and F3=8.00NF3=8.00N are applied to the block, initially at rest on the surface, at angles shown on the diagram. (Figure 1) In this problem, you will determine the resultant (total) force vector from the combination of the three individual force vectors. All angles should be measured counterclockwise from the positive x axis (i.e., all angles are...

GOAL Use the superposition principle to calculate the electric field due to two point charges. Consider the following figure. The resultant electric field  at P equals the vector sum 1 + 2, where 1 is the field due to the positive charge q1and 2 is the field due to the negative charge q2.Two point charges lie along the x-axis in the x y-coordinate plane. Positive charge q1 is at the origin, and negative charge q2 is at (0.300 m, 0). Point...
