Question
An outfielder throws a 0.148 kg baseball with velocity 30 m/s at 25° above horizontal. Ignoring air resistance: what KE did the ball have, at its peak (highest point)?

Transcribed Image Text:The image contains a list of options, each represented by a circular button, typically used for multiple-choice questions. Each option is associated with a numerical value expressed in joules:
1. 4.44 Joule
2. 2.22 Joule
3. 11.90 Joule
4. 54.7 Joule
5. 66.6 Joule
6. 0.938 Joule
7. 2.01 Joule
8. 133.2 joule
Note that the word "joule" is capitalized for most options except the last one.
Expert Solution

Step 1
Given data:
Mass (m) = 0.148 kg
Initial velocity (V0) = 30 m/s
Angle (θ) = 25°, above the horizontal
Air resistance is negligible
Required:
The kinetic energy at peak height
