# Sriking the support

Classical Mechanics Level 4

A block of mass 0.1 kg is tied to one end of a light string of length 0.1m whose other end is fixed to a rigid support as shown in the figure. The block is given a speed v from the lower most position such that $$\sqrt { 2 } <v<\sqrt { 5 }$$ . When the block just leaves the circle the string is cut and the block moves as a projectile in a parabolic path and strikes the rigid support to which the string was attached. Find $$\alpha$$ if v=$$\sqrt { \tan { \alpha } }$$ where $$\alpha$$ is an acute angle in degrees.
