The speed of third piece that weighs is .
Explanation:
Three pieces of dinner plate after falling vertically to floor and slides horizontally along the floor and goes in three different directions.
The first piece of moves along the x-axis by the speed of and the other piece of moves on the y-axis by the speed of .
Our aim is to find the speed of third piece that weighs .
Let the horizontal plane of floor be x-y plane. Before the collision there was no momentum.
Consider the components of velocity of third piece as and , and the resultant of velocity makes an angle of under the negative x-axis as shown in Figure 1.
Due to conservation of momentum equation is written as,
The another equation from conservation of momentum is written as,
The velocity by which the third piece moves is calculated as,
Therefore, the speed of third piece is .
Thus, the speed of third piece that weighs is .
