You traveled a distance of 620.075 meters if it takes you 8.5 seconds to stop.
<u>Given the following data:</u>
- Initial velocity, U = 31.3 m/s  
We know that acceleration due to gravity (a) for an object is equal to 9.8 meter per seconds square.
To find the distance traveled, we would use the second equation of motion:
Mathematically, the second equation of motion is given by the formula;

Where:
- S is the distance travelled.
- u is the initial velocity.
- t is the time measured in seconds.
Substituting the parameters into the formula, we have;

<em>Distance, S</em><em> = </em><em>620.075 meters.</em>
Therefore, you traveled a distance of 620.075 meters if it takes you 8.5 seconds to stop.

Force (f) = ? 
Acceleration (a) = 196 m/s^2
Mass (m) = 0.25 kg
F = (m) • (a) 
F = (0.25) • (196)
F = 49 N
Answer : 49 N

The sound is perceived as louder if the amplitude increases, and softer if the amplitude decreases. ( for amplitude) 
Since sound at all frequencies has the same speed in air, a change in frequency means a change in wavelength. ( for frequency)
