# What is the average force on the tennis ball?

• galtaash
In summary, average force is a measure of the overall force applied to an object over a certain period of time. It differs from instantaneous force in that it takes into account the total force over a period of time, rather than just at a specific moment. To calculate average force, the total force and time interval must be known. Knowing the average force on a tennis ball is important for understanding its impact and potential for injury, and it can be affected by factors such as the speed and angle of impact, surface conditions, and player strength and technique.

A tennis ball may leave the racket of a top player on the serve with a speed of 62.0 m/s. If the ball's mass is 0.0600 kg and it is in contact with the racket for 0.0200 s, what is the average force on the ball?

You must deduce the average force from the average acceleration (Newton'S 2 law)

if the ball went from 0 to 62m/s in 0.0200 s, then what is the average accel?

btw - you're in the wrong forum. This is the math forum and yours is a physics question. try "Introductory physics" next time.

## 1. What is the definition of average force?

The average force is a measure of the overall amount of force applied to an object over a certain period of time. It is calculated by dividing the total force by the duration of the time interval.

## 2. How is average force different from instantaneous force?

Average force takes into account the total force applied to an object over a period of time, while instantaneous force only measures the force at a specific moment in time.

## 3. How is average force calculated?

To calculate average force, you would need to know the total force applied to the object and the time interval over which the force was applied. Divide the total force by the time interval to get the average force.

## 4. Why is it important to know the average force on a tennis ball?

Knowing the average force on a tennis ball can help us understand the impact of the ball on different surfaces and how much force is needed to return the ball. It can also help in determining the durability of the ball and its potential for causing injury.

## 5. What factors can affect the average force on a tennis ball?

The average force on a tennis ball can be affected by factors such as the speed and angle of impact, the surface of the ball and the surface it bounces off of, and the air resistance. The type and condition of the ball, as well as the strength and technique of the player, can also play a role in the average force applied.
