The speed and direction of each object after the collision.
Answer to Problem 23P
The speed of ice puck after the collision
The speed of puck after the collision
Explanation of Solution
Given:
The mass of ice puck is
The initial velocity of the ice puck is
The mass of puck is
The initial velocity of the puck is
Formula used:
The expression for law of conservation of momentum is,
Here,
The expression for conservation of kinetic energy is,
Here,
Calculation:
The speed of each object using the relation of conservation of momentum is,
Given that the collision is perfectly elastic. The speed of each object using the relation of conservation of kinetic energy is,
Hence, the speed of puck after the collision
The speed of ice puck after the collision using the relation is,
Hence, the speed of ice puck after the collision
Conclusion:
Thus, the speed of ice puck after the collision
Thus, the speed of puck after the collision
