Problem 1- For the cam-follower system, the slotted bar has a constant angular velocity of 10 rad/s, and the follower A's radial position is given by:
r = 1 + 0.5 cos(2θ) ft
Determine the magnitudes of the follower's velocity and acceleration when θ = 30°.
Problem 2-The student starts from rest at the caller and runs away with a constant radial acceleration 0.5 m/s2 (with respect to the platform) as shown. The platform rotates at constant angular velocity 0.2 rad/s. Determine the magnitudes of the student's velocity and acceleration alter 3 seconds.
