A cam is designed to achieve a simple harmonic motion of a flat-faced follower. Starting from the rest

Q. A cam is designed to achieve a simple harmonic motion of a flat-faced follower. Starting from the rest, the follower rises to the maximum height of 50 mm at 180˚ of cam rotation as shown in the figure.

If the cam rotates at a uniform angular speed of 100 rpm, the speed of the follower (in mm/s) at the instance when the cam rotates 45˚ from the initial position is         

Ans: 180-190

Sol:
