A for the force to be along 0 deg the forces in the horizontal direction should be canceled by each other so the horizontal component of the force from person A is 50sin45 and the horizontal component of the person B is F sin 30 then Fsin30 =50 sin 45 then force F = 50 sin45/sin30 = 70.71N
B from the question the angle is 45 degrees with the crate
C again applying equilibrium equation along the horizontal axis 50sin45 + 10 = F sin 30 ==> 35.355+10 = f*0.5
F = 45.355 * 2 = 90.71N and yes the person B can adjust the force to keep the net acceleration of the crate along 0 degrees axis

Question 4 (force vectors) Two people are pulling on a crate through two ropes. Person A is on the left pulling toward the left with a force of 50 N at 45° and person B is on the right pulling toward the right at an angle of 30°. Here is what the situation looks like from above. The resulting acceleration of the crate is at 0°. acceleration direction person B F 30° person A 50 N 45° 130% 45% crate...

The helicopter view in the figure below shows two people pulling on a stubborn mule. (Take F1 = 111 N and F2 = 87.0 N.) An illustration shows the helicopter view of a mule being pulled along a forked road in two directions by two men. An x y coordinate system is overlaid on the image, with the origin at the mule's nose, and the mule facing in the positive y-direction. The man on the right is pulling the mule toward...
Force 1. In the picture below, Jack is pushing a crate to the right. The crate is on very good wheels so friction between the crate and the floor is so small that it can be ignored. Jack pushes with a force of 120 N and the crate accelerates to the right at a rate of 1.0 m/s a In the picture at right, Jack and Janet are both pushing the same crate with a force of 120 N each....
A worker drags a crate across a factory floor by pulling on a rope tied to the crate. The worker exerts a force of magnitude F = 460 N on the rope, which is inclined at angle θ = 35° to the horizontal, and the floor exerts a horizontal force of magnitude f = 100 N that opposes the motion. Calculate the magnitude of the acceleration of the crate if (a) its mass is 360 kg and (b) its weight...
A worker wants to turn over a uniform 1220-N rectangular crate by pulling at 53.0 ? on one of its vertical sides (the figure (Figure 1) ). The floor is rough enough to prevent the crate from slipping. A: What pull is needed to just start the crate to tip? B: How hard does the floor push on the crate? C: Find the friction force on the crate. D: What is the minimum coefficient of static friction needed to prevent...
You are a fitness trainer developing an exercise that involves pulling a heavy crate across a rough surface. You attach a rope to a crate of mass M = 45.0 kg and place it on a carpeted track. Using your physics expertise, you have already determined that the coefficient of kinetic friction between the crate and the carpet is μk = 0.430. To test the apparatus, you have one of your employees pull on the rope as hard as she...
Two people pull as hard as they can on horizontal ropes attached to a boat that has a mass of 200 kg. If they pull in the same direction, the boat has an acceleration of 1.58 m/s^2 to the right. If they pull in opposite directions, the boat has an acceleration of 0.500 m/s^2 to the left. What is the magnitude of the force each person exerts on the boat?
two people pull as hard as they can on horizontal ropes attached to a boat that has a mass of 200 kg. If they pull in the same direction, the boat has an acceleration of 1.54 m/s squared to the right. If they pull in opposite directions, the boat has an acceleration of 0.516 m/s squared to the left. What is the magnitude of the force each person exerts on the boat? Disregard any other horizontal forces on the boat....
3) A constant pulling force of 150 N applied at an angle of 21.7° above the horizontal, accelerates a crate across a rough horizontal surface. The has mass 35.2 kg, and the acceleration is 0.571 m/s. a) What is the normal force acting on the crate? b) What is the friction force acting on the crate? c) What is the coefficient of kinetic friction between surface?
