- 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.arrow_forwarde1 A double incline is setup with two ramps as shown. The left block has a mass m1, and the right block has a mass m2. The left ramp is rough with kinetic friction coefficient uy and an angle 01. The ramp on the right is frictionless with an angle 02. The pulley is massless and frictionless. Assume the system starts accelerating to the right on initial release. a) In the Space below draw a set of free body diagrams (or a single one if taking that method which is fine) to fully describe all forces in this problem. b) Find an equation for the acceleration of the system.arrow_forwardII.
