Question

Transcribed Image Text:**Problem Statement:**
A 2.91 kg particle has a velocity of \( (3.08 \, \mathbf{i} - 3.35 \, \mathbf{j}) \, \text{m/s} \).
**Task:**
(a) Find its x and y components of momentum.
- \( p_x = 8.968 \) ❌
- *Feedback:* Your response is within 10% of the correct value. This may be due to round-off error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize round-off error. (Answer in \(\text{kg m/s}\))
- \( p_y = -11.4945 \) ✔️ \(\, \text{kg m/s}\)
(b) Find the magnitude and direction of its momentum.
- Magnitude: \( 20.643 \) ❌
- *Feedback:* Your response differs from the correct answer by more than 10%. Double check your calculations. (Answer in \(\text{kg m/s}\))
- Direction: \( 308.84^\circ \) ❌ (clockwise from the +x axis)
---
**Explanation:**
In part (a), the components of momentum are calculated using the formula \( p = mv \), where \( m \) is mass and \( v \) is velocity. Each component should be calculated separately for the directions \( \mathbf{i} \) (x-axis) and \( \mathbf{j} \) (y-axis).
In part (b), the magnitude of momentum is derived using the Pythagorean theorem on the components, and the direction uses the arctangent function to find the angle relative to the positive x-axis. Errors should be checked for precision and accuracy by ensuring all calculations use sufficient significant figures.
