Question
Transcribed Image Text:2. The 12 kg block is confined to move along the smooth parabolic path.
The attached spring restricts the motion and, due to the roller guide,
always remains horizontal as the block descends. If the spring has a
stiffness of k = 10 N/m, and unstretched length of 0.5 m. The mass of
the roller and the spring can be neglected.
Determine
a) the normal force of the path on the block at the instant x = 1 m when
the block has a speed of 4 m/s.
b) the rate of increase in speed of the block at x = 1 m.
