According to law of conservation of momentum... as p=m.v so as velocity v increases the momentum also increases in the direction of motion
Answer:
Explanation:
Given
initial height 
coefficient of static friction 
When collision is elastic respective velocities after collision is
where 
and 
=initial velocities of object
and 
final velocities of object
using 
(b)Completely Inelastic
In Completely Inelastic objects stick with each other
using
1) find speed (8.8 m/s)
2) find acceleration (38.7 m/s^2)
answer is about 38.7 m/s^2
The sound comes from the speakers which produce sound waves which is the music, the volume could be changed producing a louder sound or a quieter sound which means that the speakers could produce more sound waves or less sound ways ( depends on the volume )
