A) Two objects, one 2.0 kg and the other 3.0 kg, are approaching each other equally and at 5.0 m / s. Objects collide and become one piece.
A1) Find the final velocity of the particles.
A2) Find the amount of kinetic energy lost during the collision.
A3) Assuming that the objects approach each other at a 90 ° angle before the collision (i.e. along the x and y axes) What happens to the kinetic energy loss?
B) Find the center of mass of the decent L-shaped iron bar with sides 0.40 m and 0.70 m respectively.(Consider the L shape of the rod as thin.)
