2. An air track is set to be perfectly level on a lab table, and the glider (total mass 120 grams) is attached by a string of negligible mass, over a pulley with negligible friction, to a hanging mass of 75 grams. Sketch the system, and include arrows to show all the forces acting on the two objects (glider and hanging mass). (b) Label all the force vectors with their magnitudes. (c) Write an equation for Newton's 2nd Law for each of the two objects. (d) Solve for the acceleration of the glider and the tension in the string.
I need help with this problem: A. Calculate the magnitude of the total force. B. When the fourth force is applied to the mass, it is observed that the velocity of the mass stops changing and remains constant. What are the horizontal and vertical components of the fourth force? I've tried adding up all of the velocitys and found Vtotal = 111.8 N with a direction of 26.5 deg. Which is incorrect. Below is the graph we are given.
HW1.4. 2D Moment resultant Two forces lying in the x-y plane are defined by their magnitudes and direction angles, as shown in the figure below. Force F₁ has a magnitude F₁ = 360 N, an angle 0₁ = 109°, and acts at point A (310, 0) mm. Force F₂ has a magnitude F₂ = 270 N, an angle 02 = 56°, and acts at point B = (0,385) mm. Determine the total moment about point O due to these two forces. Remember to follow the standard sign convention for clockwise (-) and counter-clockwise (+) moments. y B 10 02 F₂ F₁ A 0₁ X TEGINGEN

Mr. One is pushing a cart with a force of F1 - 15.00 N due north. Mr. Two is pushing the same cart with a force of F2 - 25.00 N due northeast. Mr. Three is pushing the cart a force F3 so that the cart is in equilibrium. Find force F3 so that F +Fz+F3=0. First, we calculate the vector sum F + F2 by component method. The x-component of F, is and the y-component is The x-component of Fz is and the y-component is Adding the components, we can express the resultant vector in unit vector component form: Since we want to find F +F;+F3-0, t follows that F- - (Fj +F). Thus, The magnitude of Fg is F3- N.
