Two forces, of magnitudes F1 = 80.0 N and F2 = 40.0 N , act in opposite directions on a block, which sits atop a frictionless surface, as shown in the figure. (Figure 1)Initially, the center of the block is at position xi = -4.00 cm . At some later time, the block has moved to the right, and its center is at a new position, xf = 5.00 cm . PART 1) Find the work W1 done on the...

Two forces act on a point particle: Fi is 40 N in the -x direction and F2 is 25 N in the -y direction. a) Find the magnitude of a third force, in N, on the particle which makes the net force zero? b) Find the direction of that force by giving an angle with respect to the + x axis, in degrees.
A cutting tool under microprocessor control has several forces acting on it. One force is F⃗ =−αxy2j^, a force in the negative y-direction whose magnitude depends on the position of the tool. The constant is α = 2.15 N/m3 . Consider the displacement of the tool from the origin to the point x= 3.80 m , y= 3.80 m . Calculate the work done on the tool by F⃗ if this displacement is along the straight line y=x that connects these...

Two forces, f1 (-6i-4j)N and f2 (-3 + 7)N, act on a particle of mass 2.00 kg that is initially at rest at origin (0.00 m, 0.00 m).(a) What are the components of the particle’s velocity at t = 10.0 s?(b) In what direction is the particle moving at t = 10.0 s?(c) What displacement does the particle undergo during the first 10.0 s?
1.14) A particle of mass m is acted upon by a net force F. As a result of the force, the particle starts from rest and moves along a curved path for which the acceleration relative to an inertial Cartesian coordinate system with an origin at the location where the particle is at rest is given by a - with At, B+Ct, and constants. You may assume that the units associated with t are seconds and = D where A,...
A cutting tool under microprocessor control has several forces acting on it. One force is F⃗ =−αxy^2j, a force in the negative y-direction whose magnitude depends on the position of the tool.
