In this question, the height you are dropping it from is irrelevant. They are simply asking to convert the height of the bounce from inches to feet.

55 inches / 12 inches/foot = 4 foot 7 inches.

There are a few ways to do the calculation in your head without a calculator.

5 feet is 60 inches (12x5). In this case you are just a little under 5 feet, so either subtract 5 inches from 5 feet, or start with a base of 4 feet (48"), and find the difference (remainder).

If you are rounding the answer... then you would round up to 5 feet since it is greater than 4.5 feet.

### How does the height a boucny ball is dropped from effect the height it bounces to?

The higher the height the ball is dropped from, the higher the height it will bounce to.

### A ball dropped from a height of 10 meters and bounces up to a height of 7 meters Assuming that the height before each bounce remain in the same ratio after how many bounces will the ball be below 2?

After the 5th bounce, it peaks at 0.168 meter. Nice problem.

### What factors affect the bounce of a dropped ball?

The factors that affect the bounce of a dropped ball include...... the height from which it is dropped; the force applied to it, if any, when dropped; the acceleration of gravity, which is different depending upon what planet you're on ; the elasticity of the ball; the density of the atmosphere, which affects "air resistance"; and the rigidity and elasticity of the surface on which the ball bounces.

### How does temperature affect the height that a dropped ball bounces?

When the ball is at a low temperature, the molecules are not flexible and bounce only to a small height. On the other hand, if the ball is warm or at a higher temperature, it will bounce longer heights.

### Is the height of a ball bounce affected by the height from which the ball is dropped?

Yes - the greater the height an item dropped the resulting bounce is higher

### Is the height of the ball's bounce affected by the height from which the ball is dropped?

Yes - the greater the height an item dropped the resulting bounce is higher

### Is the height of a ball's bounce affected by the height from which the ball is dropped?

Yes - the greater the height an item dropped the resulting bounce is higher

### Is there a link between the height the ball is dropped from and the height to which it bounces?

Yes. Under ideal circumstances - no air resistance, elastic collision (i.e., perfect bounce), the ball should bounce back to the same height from which it was dropped, due to conservation of energy. In practice, some energy is always lost, both due to air resistance and to a non-perfect bounce.

### How many times will a ball bounce?

It depends what height you drop the ball and what surface the ball is being dropped on.

### When a golf ball is dropped to the pavement it bounces back up?

When a golf ball is dropped onto the pavement, it compresses upon impact and stores some of the energy. This stored energy is then released, causing the ball to bounce back up into the air. The elasticity of the ball and the pavement's surface play a role in dictating the height and speed of the bounce.
