# HW 9 - Force and Motion

## Item 13

**Context:**
Unless otherwise stated, all objects are located near the Earth's surface, where \( g = 9.80 \, \text{m/s}^2 \).

A hockey puck impacts a goalie's plastic mask horizontally at 124 mi/h and rebounds horizontally off the mask at 45 mi/h.

### Part A

If the puck has a mass of 176 g and is in contact with the mask for 20 ms, what is the magnitude of the average force that the puck exerts on the mask?

*Express your answer using two significant figures.*

\[ 
F = \boxed{\,\,\,\,\,} \, \text{N} 
\]

*(Box for submission of answer)*

### Part B

What is the direction of the average force that the puck exerts on the mask?

- ( ) same direction as the rebounded puck
- (✔) opposite direction to the rebounded puck

*(Option buttons for selecting answer)*

### Physics Problem: Calculating Speed on Ice

**Problem Statement:**

Assuming that this average force accelerates the goalie (neglect friction with the ice), with what speed will the goalie move, assuming she was at rest initially and has a total mass of 90 kg?

**Instructions:**

- Express your answer using two significant figures.

**Input Box:**

A field is provided for inputting the calculated velocity (\( v \)) with the unit m/s.

**Submit Button:**

A "Submit" button is available for submitting your answer.

**Additional Options:**

- "Request Answer" is available if needed.

This exercise demonstrates a classic physics problem focusing on concepts of force and motion without the influence of friction. Use the formula \( F = ma \) to find the acceleration and then \( v = u + at \) to find the velocity, where \( u \) is the initial velocity (0 m/s, in this case), \( a \) is the acceleration, and \( t \) is the time.
