A ball is thrown in air . What are its velocity and acceleration at the highest point ?

Text Solution

AI Generated Solution

To solve the question regarding the velocity and acceleration of a ball thrown in the air at its highest point, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Motion**: When a ball is thrown into the air, it follows a projectile motion. At the highest point of its trajectory, the vertical component of its velocity becomes zero, while the horizontal component remains unchanged. 2. **Acceleration at the Highest Point**: ...
