Position of a Ball as a Function of Time

What is the initial position of the ball?

The position of a ball as a function of time is given by x=(4.8m/s)t (−9m/s2)t2.

Answer:

The initial position of the ball is 0 meters.

To find the initial position of the ball, we need to determine the value of x when t is equal to zero. The initial position represents the position of the ball at the starting point, which corresponds to t = 0.

Given the equation x = (4.8 m/s)t - (9 m/s^2)t^2, we can substitute t = 0 into the equation:

x = (4.8 m/s)(0) - (9 m/s^2)(0)^2

x = 0

Therefore, the initial position of the ball is 0 meters.
