Question

An Australian emu is running due north in a straight line at a speed of 13.0 m/s and slows down to a speed of 9.70 m/s in 2.30 s. (a) What is the magnitude and direction of the bird’s acceleration? (b) Assuming that the acceleration remains the same, what is the bird’s velocity after an additional 1.30 s has elapsed?

**Physics Problem: Deceleration of an Emu**

An Australian emu is running due north in a straight line at a speed of 13.0 m/s and slows down to a speed of 9.70 m/s in 2.30 s.

**Problem (a):**
What is the magnitude and direction of the bird’s acceleration?

**Problem (b):**
Assuming that the acceleration remains the same, what is the bird’s velocity after an additional 1.30 s has elapsed?

**Answer format:**

(a)
- **Number:** [____]
- **Units:** [____]

(b)
- **Number:** [____]
- **Units:** [____]

Explanation:
- Input the numerical values in the boxes next to "Number."
- Select the appropriate units from the dropdown menu next to "Units."

This problem requires the application of the basic kinematic equations to find acceleration and then subsequent velocity.

*Note: The text is followed by fields to input numerical answers and select the correct units.*
