A particle is acted on by forces given, in newtons, by vector F_1 = 2.77 cap i - 14.2 cap j and vector F_2 = 2.98 cap i + 4.36 cap j. (a) what is the x component and (b) y component of the force vector F_3 that balances the sum of these forces? (c) What angle does vector F_3 have relative to the +x axis?

You are told that an object has zero acceleration. Two forces on the object are: F_1 has magnitude 2.4 N at 45 degrees above the +x-axis and F_2 has magnitude 4.8 N at 37 degrees below the -x-axis. What is the third force that must be acting on the object? THE ANSWER ALREADY PROVIDED IS CONFUSING, I THINK A) The vector F_3 has an x-component 5.5 N in the -x-direction and a y-component 4.6 N in the -y-direction. B) The...

Three forces, F_1 = 40 N, F_2 = 20 N and F_3 = 10 N, are acting on a block of mass 4 kg as shown. The block is sitting on a horizontal surface with coefficient of kinetic friction mu_k = 0.12. The angle between F_1 and F_2 is 30 degree. What is the magnitude of: a) the friction force k_k? b) the resulting acceleration of the block in x-axis?

In this lab you will be given two different sets of vectors to add together. In Activity 1, you will add position vectors: in Activity 2 you will add forces. Vector addition is an important concept in physics. To be well prepared for the lab you need to solve the following example. Make sure to show all your work in detail. Write the equations first, and then plug in the numerical values. Do not forget to do unit conversions. Use...

Three forces acting on an object are given F_1 = (-2.45i - 2.40j)N, F_2 = (5.40i)N, and F_3 = (43.5i + 47.0j)N. The object experiences an acceleration of magnitude 3.50 m/s^2. What is the direction of the acceleration? What is the mass of the object? If the object is initially at rest, what is its speed after 18.0? What are the velocity components of the object after 18.0s? A bag of cement of weight 500 N hangs from three wires...

A 20 kg box s initially at rest. Two forces drag. it across the floor, F_1 = 35 N i and F_2 = 35 N j, which cause a displacement of 3.5 m Imagine the x-y plane lies on the floor. (a) Draw the displacement vector and show (no need to calculate) the direction in which the package moves? (b) How much work is done by each force individually (F_1 and F_2)? (c) The coefficient of kinetic friction between the...

As you will see in a later chapter, forces are vector quantities, and the total force on an object is the vector sum of all forces acting on it. In the figure below, a force F1 of magnitude 6.10 units acts on an object at the origin in a direction θ = 35.0° above the positive x-axis. A second force F2 of magnitude 5.00 units acts on the object in the direction of the positive y-axis. Find graphically the magnitude...

If F1 stands for a force vector of magnitude 30.0 N and is parallel to +x axis and F2 stands for a force vector of magnitude 40.0N making an angle of 60 degrees with the +x axis what is the magnitude of the resultant obtained by the vector addition of these two vectors using the analytical method?
