Question

(b) In an elastic collision (correctly assign True or False to all statements),
Momentum is conserved but not the internal energy.
O True
O False

O True
O False
Both momentum and internal energy are conserved.
O True
O False

1. A 65-kg ice hockey goalie, originally at rest, catches a 0.145-kg hockey puck slapped at him at a
velocity of 35 m/s. Suppose the goalie and the ice puck have an elastic collision and the puck is
reflected back in the direction from which it came.
A sketch from the animation from Part 1 should look like this. Note the subscripts i and f indicate
velocities before and after the collision, respectively. The subscripts p and g represent the puck and
the goalie, respectively.

Consider: How many knowns are there and how many unknowns? How many equations do you need
to solve for the unknowns? Can you identify the equations?
(a) What would you consider a system in this collision?

Expert Solution

Step 1: Introduction

Since you have asked multiple questions, we will solve the first question for you. If you want any specific question to be solved then please specify the question number or post only that question.

The momentum is the product of mass and its velocity. The SI unit of momentum is kgm/s. The conservation of momentum states that the momentum before the collision is equal to the momentum after the collision. There are two types of collisions

1) Elastic collisions

2) Inelastic collisions
