Question

Скорость теннисного мяча при подаче составила 210 км/ч. За какой промежуток времени мяч пролетит через весь корт (23,77 м)?

Answer 1

Calculation of Time Taken by Tennis Ball to Cross the Court

To calculate the time taken by a tennis ball to cross the court, we need to know the speed of the ball and the distance it needs to cover.

Given: - Speed of the tennis ball during the serve: 210 km/h - Length of the tennis court: 23.77 m

To calculate the time taken, we can use the formula:

Time = Distance / Speed

Converting the speed from km/h to m/s: - 210 km/h = 210 * (1000/3600) m/s = 58.33 m/s

Substituting the values into the formula: - Time = 23.77 m / 58.33 m/s = 0.408 seconds

Therefore, the tennis ball will take approximately 0.408 seconds to cross the entire court.
