1. A tennis ball is launched at an angle of 44° with a velocity of 27 m/s. How high does it go in 2.2 s? How far does it go in 2.2 s? What are the component velocities at its highest point?
---
**Explanation:**
This problem involves projectile motion, which is a common topic in physics. To solve the problem, you should:
- Break the initial velocity into horizontal and vertical components using trigonometric functions (sine and cosine).
- Use kinematic equations to determine the tennis ball's motion in both the vertical and horizontal directions.
- At the highest point, the vertical velocity component is zero. The horizontal component remains constant if air resistance is neglected.
The problem tests understanding of vectors, angles, and basic kinematics.
