Since the motion of P is being described here in terms of polar variables of r and θ, it is recommended that you use a polar description for your forces and acceleration. Use the Four-Step solution ...

Master the fundamental techniques of classical mechanics to analyze and solve projectile motion problems with confidence. In this video, we break down key concepts such as kinematics, velocity, ...

Note that since the top contact point of the disk rolls without slipping on the upper fixed surface, this contact point has zero velocity. In addition, the horizontal component of acceleration of that ...
