Particle P moves in a way that it is constrained to move along the parabolic-shaped guide, as well as within the vertical slot. Your task here is to determine the reaction forces acting on P by the guide and the slot that are needed to enforce these motion constraints.<\/p>\n

As you watch the animation above for the motion of P, why is the acceleration of P always pointing in the y-direction?<\/p>\n

Hints<\/span>:<\/strong>
\n<\/em>You should follow the four-step solution plan described in the lecture book, and as discussed in lecture:
\nStep 1: Free body diagram (FBD)<\/strong><\/em> – Draw an FBD of P alone.
\nStep 2: Kinetics<\/strong><\/em> – Write down the Cartesian components of Newton’s 2nd law for P.
\nStep 3: Kinetics<\/strong><\/em> – You need kinematics here to related the known x-components of velocity and acceleration of P to its y-components.
\nStep 4: Solve<\/strong><\/em> – You will have two equations and two unknowns. Solve these for the two reaction forces.<\/p>\n
