Question

A racket ball is struck in such a way that it peaves the racket with a speed of 4.89 m/s in the horizontal direction. When the ball hits the court, it is a horizontal distance of 1.96 m from the racket. What is the time taken by the ball to reach the court?

Answer 1

The time taken by the racket ball to reach the court is calculated by dividing the distance by the velocity, which results in approximately 0.401 seconds.

Step-by-step explanation:

To calculate the time taken by the racket ball to reach the court, we can use the formula that relates the distance traveled, velocity, and time for uniform motion:

distance = velocity × time

Given that the horizontal velocity of the ball is 4.89 m/s and the distance it covers is 1.96 m, we can rearrange the formula to solve for time:

time = distance / velocity

time = 1.96 m / 4.89 m/s

Using a calculator for this division gives:

time = 0.401 seconds

Therefore, the ball takes approximately 0.401 seconds to reach the court.
