## What is the contact time between the ball and the bat?

The contact time between the baseball and bat is less than 0.001 seconds (a little less than one frames of the movie). Other measurements suggest a contact time of about 0.7 milliseconds during realistic playing conditions. The ball experiences a significant amount of deformation during the collision.

## What is the speed of a .145 kg baseball if its kinetic energy is 109 J?

The baseball with a mass of 0.145kg and kinetic energy of 109J has a velocity of around 39.1 m/s.

## Can a baseball have the same momentum as a truck?

Yes, because if the truck was not moving while the baseball was moving, the total momentum of the truck would be zero, therefore the baseball would have more momentum.

## What is the mass of a baseball in KG?

Consider a baseball weighing 5.125oz (mass = 0.145kg) which approaches the bat at a speed of 90mph (40.2m/s).

## How many kilograms is a baseball?

A regulation baseball is 9 to 9.25 inches (229 to 235 mm) in circumference i.e. 2.86 to 2.94 inches (73 to 75 mm) in diameter, with a weight of 5 to 5.25 ounces (0.142 to 0.149 kg).

## What is the formula for speed in kinetic energy?

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

## What is the kinetic energy of a ball of mass 200 grams moving at a speed of 20 ms?

Answer is 40J. A ball of mass M is moving with speed V .

## How do you calculate kinetic speed?

## What is impulse equal to?

Impulse ( F Δ t ) Product of the average force exerted on an object and the time interval during which the force is exerted. Impulse is equal to the change in momentum ( ) and is sometimes represented with the symbol .

## How is momentum used in baseball?

When the bat collides with a ball, you are transferring the momentum (the product of mass times velocity) from the bat to the ball. To maximize the momentum of the bat, you can either increase the mass of the bat or swing the bat faster.

## What is an example of momentum in baseball?

Example: Hitting a pitched baseball. A baseball of mass 0.14 kg is pitched at a batter with an initial velocity of -38 m/s (negative is towards the bat). The bat applies an average force that is much greater than the weight of the ball, and the ball departs from the bat with a final velocity of +58 m/s.

## What is a ball in baseball?

Ball: A pitch which does not enter the strike zone and is not struck at by the batter. Base: The four points of the baseball diamond (first through third bases and home plate) that must be touched by a runner in order to score a run.

## What is the nickname for a baseball field?

A baseball field, also called a ball field or baseball diamond, is the field upon which the game of baseball is played.

## How many cm is a baseball?

The appearance of the Baseball is regulated by Major League Baseball. Baseballs have a diameter between 2.86”-2.94” (7.3-7.5 cm) and circumference from 9”-9.25” (22.9-23.5 cm).

## What is the reaction time of a bat?

Sometimes we also see reaction times of only 20 milliseconds in bats, for instance in response to loud sounds, but that is a simple reflex reaction that does not require brain work.

## How do you time a ball when batting?

## Where should the bat make contact with the ball?

## What is timing in cricket batting?

Timing is all about hitting the ball at the right ‘time’. It is about the face of the bat making contact with the ball at exactly the right time for maximum efficiency and effectiveness. There are a number of factors that can help you improve your timing.
