A pellet of mass 8.8 g embeds itself in a wooden block of 450 g which is suspended by a light in-extensible string. After the collision the block reaches a max height of 0.63 m. Calculate the initial velocity of the pellet.

Max Gravitational Potential energy of combined mass:GPE = m x g x h= ( 0.0088 kg + 0.450 kg ) x 9.81 ms^-2 x 0.63 m = 2.84 J
Therefore Kinetic energy of the combined mass at the collision = 2.84 JKE ...
