A ball is dropped on to the floor from a height of 20m it rebounds to height of 10m if the ball is in contact with floor for 0.1 second what is the average acceleration during contact?
To find the average acceleration during contact, we need to use the formula for acceleration:
acceleration = (change in velocity) / (time)
In this case, we don't know the change in velocity yet, so let's calculate it first.
The ball is dropped from a height of 20m and rebounds to a height of 10m. The change in velocity can be calculated using the equations of motion for freefall.
Using the equation:
change in velocity = √(2 * acceleration * height)
Where:
acceleration is the acceleration due to gravity (approximately 9.8 m/s^2),
and height is the initial height (20m in this case).
Substituting the values, we get:
change in velocity = √(2 * 9.8 * 20)
Now we can find the change in velocity.
