Answer» SOLUTION : `tan45^@=(h)/(l_0)` `(4)/(3)=(h)/(l_0)impliesh=(4l_0)/(3)` `cos53^@=(l_0)/(l_0+x)implies(3)/(5)=(l_0)/(l_0+x)impliesx=(2l_0)/(3)` Mechanical ENERGY conservation between B and A `mgh+(1)/(2)kx^2=(1)/(2)mv^2` `v^2=2gh+(kx^2)/(m)=2gxx(4l_0)/(3)+(k)/(m)xx(4l_0^2)/(9)` `v=sqrt((4l_0)/(3)(2g+(kl_0)/(m)))` |
