Solved in 4 steps
- A block with a mass m is pushed up an inclined rough surface by a horizontal force F as shown. If the block is being pushed up at a constant speed, find the magnitude of the applied force F, given that theta =35 degrees , m = 5 kg, and the kinetic frictional coefficient between the block and the inclined surface mu_k = 0.2Find the distance x along ab at which a horizontal force of 300n should beTwo forces act on a single point. The first force is 200N in the direction of S30◦W and the secondforce is 150N due east. Write each of these forces in vector form and then find the magnitude of theresultant vector.
- Find the horizontal forceAn object with weight W is dragged along a horizontal plan by a force acting along a rope attached to the object. If the rope makes an angle theta with a plane, then the magnitude of the force is: F = (mu)W/((mu)sin(theta)-cos(theta)) where mu is the coefficient of friction. For what theta, F is smallest?Consider a pair of forces, one having a magnitude of 20N and the other magnitude of 12N .What maximum net force is possible for these two forces? What is the minimum net force possible?
- Determine the magnitude F and the angle theta, if the resultant of the two forces acting on the block is to be a horizontal 80-N force directed to the right.A block of mass M is pulled by a force T at an angle theta about the horizontal and moves at constant speed over a rough surface (with friction) .The magnitude of the friction force is:If the force vector Ai + Bj +Ck has magnitude equal to 50 N,, Then the y-axis component of this force is?
