magnitude of the net force

1. Four horses are pulling a wagon down a street in a parade. the front two horses can each pull 1500N (forward) on their reigns, while the back two horses can each pull 1200 N (forward). the force of friction of the wagon wheels on the ground is 550 N (backward). Starting with a free body diagram, calculate the net force on the wagon.  2. What is the displacement and direction of the resultant vector if a soccer player runs 55.0m at an angle of N27 degrees West, and then runs 23.0m at an angle of S5 degrees West from her new location? Draw a diagram, please! 3. A golf ball, which is lying directly on the ground, is hit with a velocity of 22m/s at an angle of 30 degrees above the horizontal. Determine the golf balls: a). time of flight b). range c). maximum height

Express the following quantities in SI units:  23.4 grams = 2.34 x 10^-2  124 millimeters =  1 hour and 24 min =   0.12 centimeters =

Two forces are exerted on an object: a force A with an x-component of 9.00[N] and a y-component of -2.40[N], and a force B with an x-component of -13.30[N] and a y-component of 23.60[N]. Assuming these are the only two forces on the object, what is the magnitude of the net force on the object? Express your answer in N.

What is T?

2. In mechanics, force is a vector quantity and has a unit of Newtons (N). The force F₁ with a magnitude of 54.0 N is applied at an object at the origin in the direction of 25° above the negative x-axis. A second force F₂ with a magnitude of 41.0 N is applied at the same object in the direction of 68° above the positive x-axis. Determine the magnitude and direction of the resultant of the two forces.

1. Dislocated shoulder. Another vector example is force, which has an SI unit of Newtons (N). Just like displacement, we can add two or more forces. Now, consider a patient with a dislocated shoulder placed in a traction apparatus as shown in figure 1. The vectors A and B have equal magnitudes and must combine to produce an outward force of +5.60Ni. What are the magnitudes of A and B? Figure 1:

Two dogs pull horizontally on ropes attached to a post; the angle between the ropes is 80.0∘. Dog A exerts a force of 250 N , and dog B exerts a force of 300 N . a. Find the magnitude of the resultant force. b.

Two blocks are connected by a (massless) string that runs over a (massless, frictionless) pulley as shown. Assume there is no friction between block 1 and the surface of the incline. 40° 2 If m₁ = 3.9 kg and m₂ = 5.9 kg, what is the tension in the string? Express your answer in N, to at least one digit after the decimal point.

All the ffollowing require vector diagrams:   1. Two horses are used to pull a carriage.  They act at 30⁰ to each other.  One horse pulls with a 550 N force and the resultant force is 1000 N.  With what force is the second horse pulling the carriage? 2. A 1000 N crate rests on a 20⁰ incline.  Resolve the force of the crate into components that are parallel and perpendicular to the incline.  State the magnitudes of the components. 3. A swimmer is swimming at 1 knot (nautical miles per hour) on a heading of N30⁰W.  The current is flowing at 2 knots towards a bearing of N10⁰E.  Find the velocity of the swimmer, relative to the shore. 4. A ski chairlift is suspended between two towers that are 60 m apart.  When the chairlift is 20 m from one tower, the cable sags 1 m.  The chairlift is loaded with four skiers with a combined weight of 250 N (including the mass of the chair).  What are the tensions in the two parts of the cable?
