**Physics Problems: Understanding Motion**

2) What is the displacement of a ball that is thrown up at 14.0 m/s one second after thrown?

3) How long does it take a ball to hit the ground when dropped from 42.0 meters?

4) What is the final velocity of a ball the moment before it strikes the ground from 42.0 meters?

5) What is the final velocity of a bicycle starting at 3.00 m/s accelerating at 1.70 m/s² for 5.00 seconds?

---

These problems explore fundamental concepts in kinematics, focusing on topics such as displacement, time of flight, and final velocity. They help in understanding how objects move under the influence of gravity and other forces.

**Physics Problems on Motion and Velocity**

6) **Problem:** What is the initial velocity of a ball thrown down off a building that hit the ground at 33 m/s after 4.0 seconds?

7) **Problem:** What was the average velocity of a plane that takes 330.0 seconds to travel 42760.0 meters?

8) **Problem:** You are driving at 15.0 m/s when you hit the gas to pass another car. What is your final velocity if you accelerated at 4.2 m/s² for 40 meters?

**Explanation of Concepts**:

- **Initial Velocity:** The velocity of an object at the start of its motion.
- **Average Velocity:** Total displacement divided by time taken.
- **Final Velocity:** The velocity of an object at the end of its motion after undergoing acceleration.
