Question

How long will a ball take to fall if it starts from rest and moves down for 44.0 m

Answer 1

The ball will take approximately 2.10 seconds to fall.

Step-by-step explanation:

To calculate the time it takes for a ball to fall from rest, we can use the equations of motion. In this case, the ball is moving downward, so we can use the equation

`s = ut + (1/2)at^2,`

where u is the initial velocity, t is the time, and a is the acceleration due to gravity. Since the initial velocity (u) is zero, the equation simplifies to

`s = (1/2)at^2.`

Plugging in the values, we have

`44.0 = (1/2)(9.8)t^2.`

Solving for t, we find that it takes approximately 2.10 seconds for the ball to fall.
