Quick Answer: How Much Did The Tennis Ball Compress Physics Question?

2 Answers. The ball accelerates at a rate of −1414ms2 and compresses by 8.66mm.

How do you find the rebound velocity of a ball?

Dividing through by 0.4 gives us is equal to 11.5. If a ball of mass 400 grams collides with a vertical wall at a speed of 16 meters per second, where the wall exerts an impulse of 11 newton seconds on the ball, then the rebound speed is equal to 11.5 meters per second.

What is the velocity of a tennis ball?

The terminal velocity of a tennis ball is about 21 m/s.

How far will a ball drop in 1 second?

Example. The first equation shows that, after one second, an object will have fallen a distance of 1/2 × 9.8 × 12 = 4.9 m. After two seconds it will have fallen 1/2 × 9.8 × 22 = 19.6 m; and so on.

What is G in free fall?

A free-falling object has an acceleration of 9.8 m/s/s, downward (on Earth). A matter of fact, this quantity known as the acceleration of gravity is such an important quantity that physicists have a special symbol to denote it – the symbol g.

How do you calculate a rebound?

This statistic shows how often the player or team can rebound the ball and limit the number of scoring chances for the offense. It is calculated by dividing the total number of defensive rebounds generated by the player or team by the total number of rebounds available. Multiply the result by 100 to get a percentage.

What is the acceleration of a bouncing ball?

On earth, this acceleration due to gravity is 9.8 m/s2 (g= 9.8 m/s2). This means, in essence, that for every second for falling, the ball’s velocity will accelerate by 9.8 m/s.

What is the formula for coefficient of restitution?

v 2−v 1=−e(u 2−u 1). This formula is Newton’s law of restitution. The coefficient of restitution always satisfies 0≤e≤1. When e=0, the balls remain in contact after the collision.

Why do balls eventually stop bouncing?

When the basketball hits the floor, some kinetic energy that the ball has is transferred into another form of energy. This is because the basketball had an inelastic collision with the ground. After a few bounces, it stops bouncing completely. The energy has left the ball!

How is velocity used in tennis?

In tennis, max speed can be seen through arm speed (and hence, racquet speed) on all serves and groundstrokes. The highest velocities occur just before contact. Furthermore, research has proven that increases in power and force in high-velocity movements occur with high-velocity training.

Why does a tennis ball not slow down very quickly when hit?

The under-inflated ball encounters somewhat less air resistance (air drag). It would therefore not slow down as quickly and would be able to travel further.

Who has the fastest serve in tennis?

The fastest tennis serve ever recorded is an astonishing 263.4 km/h (163.7 mph) in 2012 by Sam Groth.

What is the cost of one tennis ball?

Yellow Cricket Tennis Ball, Rs 16 /piece Nisha Enterprises | ID: 17694794188.

Has anyone ever been killed by a tennis ball?

Richard Wertheim ( c. 1923—September 15, 1983) was an American tennis linesman who suffered a fatal injury on September 10, 1983, during a match at the 1983 US Open. He was injured when Stefan Edberg sent an errant serve directly into his groin. Wertheim was sitting in a chair and officiating at the center line.
