Please answer this NEATLY, COMPLETELY, and CORRECTLY for an UPVOTE. P is known to have a value equal to 260 lbs. Determine (a) the value of α so that the resultant of the three forces is to be vertical, and (b) the magnitude of the resultant force. Lastly (c) what are the components of the resultant force when resolved about the w and ν axis?
1. Consider a cart moving along a horizontal table at constantvelocity. On your own, sketch below the forces you believe are acting on the cart at threedifferent times (three different snaps). Be sure to indicate the relative size of those forces by therelative sizes of your drawn vectors. (Assume no friction.)
The diagram shows overhead views of four situations in which forces act on a block that slides on a frictionless ice surface. In which situations would it be possible for the block to move along the floor with a constant velocity? (Assume the magnitudes of the forces can be adjusted slightly). I do not understand this at all. I know gravitational force is downwards, and frictional force is opposing the pushing force, but how do I solve this?
Four forces in a plane, act at a point O, the values and directions of the forces are being as shown in figure 2. Prove that the direction of the resultant of this force is 18.8⁰. Demonstrate the steps that you will take to determine the value of the magnitude of the resultant.
With what force in the rightwards direction, Fx, should the mother push? Note that if you think the force exerted by the mother should be toward the left, your final answer Fx should be negative. Express your answer in terms of W, Lend, w, L2, L3, and h.
The contestant now pulls the block of ice with a rope over his shoulder at the same angle above the horizontal as shown below. Calculate the minimum force Fhe must exert to get the block moving. (b) What is its acceleration once it starts to move, if that force is maintained?
(Figure 1)Block 1, of mass m1, is connected over an ideal (massless and frictionless) pulley to block 2, of mass m2, as shown. Assume that the blocks accelerate as shown with an acceleration of magnitude a and that the coefficient of kinetic friction between block 2 and the plane is μ. Find the ratio of the masses m1/m2. Express your answer in terms of some or all of the variables a, μ, and θ, as well as the magnitude of the free-fall acceleration g.
A steel ball (S) of mass 3.5 kg is suspended from two strings connected to the points A and B as shown in the picture. The string connecting A to S is at an angle of θ = 33∘ from the vertical, while the string connecting B to S is horizontal.Calculate the magnitude of the tension T→BS. I know that I need to be using Newtons second law, but that is all that I can think of. Can anyone please help me solve this?
You pull on a crate using a rope as image, except the rope is at an angle of 20.0 ∘ above the horizontal. The weight of the crate is 325 N, and the coefficient of kinetic friction between the crate and the floor is 0.270. 1) Make 2 free body diagrams, 1 for the real forces, 1 for the components. 2) Write out the expressionfor Fnet for both the vertical and horizontal directions. 3) If you write out the expression for friction you now have 3 equation and 3 unkowns. What is the tension in the rope?
Just need part D and E answered Consider a 5 kg mass placed on a frictionless incline that makes an angle of 30 degrees with the horizontal. A rope is attached and positioned over a pulley at the top of the incline. A 6 kg mass is suspended from the free end. a) On a separate diagram, draw the FBD of the hanging block, , and label all the forces acting on it. b) On a separate diagram, draw the FBD of Block and label all the forces. c) Write down Newton’s second law for each block, and for each relevant co-ordinate axis. d) From your equations in part d), write down an expression for the acceleration of the system. e) Calculate the acceleration and the tension in the chord
Problem 6: At a post office, a parcel that is an m kg box slides down a ramp inclined at an angle θ with the horizontal, as shown. The coefficient of kinetic friction between the box and the ramp is μK, and the coefficient of static friction for the same is μS. Notice that the coordinate axes have been chosen with the x axis directed up the incline, as shown. Part (e) Input an expression for the acceleration of the box in the x direction consistent with the coordinate axes on the diagram. Express your answer in terms of the mass of the box, m, the acceleration due to gravity, g, the angle of the incline, θ, and appropriate coefficients of friction. The coefficient of kinetic friction between the box and the ramp is μK, and the coefficient of static friction for the same is μS.
