A child drops a ball from a window that is 24 feet high. The ball strikes the ground in 3.0 seconds. What is the velocity of the
choli [55]

Answer:

The velocity of the ball the instant before it strikes the ground is 30m/s

Given the data in the question

Since the ball was initial at rest before it was dropped by the child

Initial velocity;  

Time taken for the ball to hit the ground;  

Final Velocity;  

To find the velocity of the ball the instant before it hits the ground

We use the First Equation of Motion:

Where v is the final velocity, u is the initial velocity, t is time and a is the acceleration.

Now, since the ball was thrown from a particular height (window), it is under gravity and acceleration due to gravity;  

Hence, the equation becomes;  

We substitute our values into the equation

Therefore, the velocity of the ball the instant before it strikes the ground is 30m/s.
