# Linear Motion Question: Ball thrown in the air

• coffee38392
In summary, a ball is thrown upwards from a building of height 2x with an initial velocity of v1. The velocity when it hits the ground is -v2. The question asks for the height of the ball when it is at maximum speed, which is at the moment it hits the ground. Therefore, the answer would be 0x. However, it is worth noting that this problem is poorly stated and may require clarification.

A ball is thrown upwards from a building of height 2x with an initial velocity of v1. The velocity when it hits the ground is -v2. What is the height of the ball when it is at maximum speed?

Since it is at its max speed when it hits the ground, would the answer just be 0x?

You should be using the homework template, but yes, you are right. This is a ridiculously stated problem. Are you sure you copied it over correctly?

## 1. How does the initial velocity affect the motion of a ball thrown in the air?

The initial velocity of a ball thrown in the air determines how far and how high the ball will travel. The greater the initial velocity, the further and higher the ball will go. This is because initial velocity is a measure of the speed and direction at which the ball is thrown.

## 2. What factors affect the trajectory of a ball thrown in the air?

The trajectory of a ball thrown in the air is affected by several factors such as initial velocity, angle of release, air resistance, and gravitational force. These factors work together to determine the path that the ball will follow.

## 3. How does the angle of release affect the motion of a ball thrown in the air?

The angle of release, or the angle at which the ball is thrown, has a significant impact on the motion of a ball thrown in the air. A higher angle of release will result in a higher arc and a longer flight time, while a lower angle of release will result in a shorter arc and a shorter flight time.

## 4. What is the maximum height reached by a ball thrown in the air?

The maximum height reached by a ball thrown in the air is dependent on the initial velocity and angle of release. It is also affected by the force of gravity and air resistance. In ideal conditions, the maximum height reached by a ball thrown in the air is when it reaches its highest point before falling back to the ground.

## 5. How does air resistance affect the motion of a ball thrown in the air?

Air resistance, also known as drag, slows down the motion of a ball thrown in the air. It is caused by the friction between the ball and the air molecules as it travels through the air. The greater the air resistance, the shorter the distance the ball will travel and the shorter the flight time will be.
