Two objects of the same mass move with unknown angle relative to each other and collide. The collision is completely inelastic. Their initial speeds were the same, after the collision they move together with the half of their initial speed. a) What was the angle between their initial velocities? b) How much of their energy (in %) was lost due to collision?

Problem 5
Two objects of the same mass move with unknown angle relative to each other and collide. The
collision is completely inelastic. Their initial speeds were the same, after the collision they move
together with the half of their initial speed.
a) What was the angle between their initial velocities?
b) How much of their energy (in %) was lost due to collision?
Important: Draw a sketch defining a coordinate system: x- and y-axes and the origin.
Without this sketch the problem will be considered as not-solved!
