What is the speed of a tennis ball on the return of a serve?

What is the speed of a tennis ball on the return of a serve?

Short Answer. The speed of a tennis ball can be as fast as the serve on the return even if the racket is not swung very fast because of the momentum imparted by the racket on the ball during its return.

What is the momentum of a tennis ball?

The magnitude of the instantaneous momentum of a 57-g tennis ball is 2.7 kgm/s.

Where is the speed of a tennis serve measured?

Velocity. The serve speeds you see on courtside digital displays are measured just as the ball leaves the racquet.

What is the velocity of a tennis ball?

Between 122 feet per second( 83.2 mph ) at air temperature of 20C and 123 feet per second ( 83.8 mph ) at 0C. That’s assuming that the ball is hit perpendicular to the baseline, the net is 3.5 feet high, no spin on the tennis ball and no cross wind.

What is the momentum of a 6.0 kg ball?

Expert-Verified Answer Mass of the ball = 6 kg. Velocity = 2.2 m/s. ∴ p = 13.2 kgms⁻¹. Hence, the momentum of the ball is 13.2 kgms⁻¹.

What is the formula for the momentum of the ball?

The momentum, p , of a body of mass m which is moving with a velocity v is p=m×v=mv p = m × v = m v .

What is the formula for momentum in physics class 11?

The product of the units of mass and velocity is the unit of Momentum. To find the momentum, we can use the simple formula: P=mv, where P is the momentum.

How is speed used in table tennis?

When playing topspin strokes, you can contact the ball at several points along its path to produce varying amounts of spin and speed. For maximum spin, contact the ball as it descends. For fast topspin, play the ball at the top of the bounce.

How do you measure the speed of a rotating shaft?

A stroboscopic system is used for measuring the speed of a rotating shaft. The shaft has one target mark on it. The maximum strobe rate at which synchronism is achieved is r1 flashes per minute. The next lower flash rate at which synchronism is achieved is r2 flashes per minute.

What is the speed of a women’s tennis serve?

How fast is an average tennis serve? The standard speeds for professional players are around 120mph (190-200 km/h) for the men, and 105mph (170-180 km/h) for the women.

How fast is terminal velocity for a tennis ball?

Due to air resistance the tennis ball would reach a terminal velocity of about 100 km/hour. The ball would happily bounce unharmed. To put it in perspective, a good pro tennis player can serve at 150 km/hour. As for a person being harmed, how would you like to be hit in the head by a 100 km/hour tennis ball?

How do you return a slow serve in tennis?

What is the physics behind tennis?

How do you return fast balls in table tennis?
