## Fundamentals of Physics Extended (10th Edition)

Speed of block $=(gd/2)^{0.5}$
Acceleration of block $=\frac{g}{4}$ Displacement $=d$ velocity=$v$ By using the Equation of Kinematics $v^{2}=u^{2}+2ad$ and substituting the expressions above, $v^{2}=0+2(\frac{g}{4})d$ $v^{2}= \frac{gd}{2}$ $v = (gd/2)^{0.5}$
