I think they decrease echo and reduce noise, they do this by either absorbing vibrations or by scattering the sound so that echoes arrive at different times rather than reverberating as a standing wave. An echo is a reflection of a sound that arrives at the listener with a delay after the direct sound. The delay is usually proportional to the distance of the reflecting surface from the source and the listener.
In your question where as a golf ball is struck at a ground level and the speed of the ball as a function of time is in the figure where time t=0 and va = 16m/s and vb=32m/s. The following is the answer:
a) How far does the golf ball travel horizontally before returning to ground level?
-<span>80m</span>
<span>(b) What is the maximum height above ground level attained by the ball?
</span>-39.87m
Hello!
A force of 5 N produces an acceleration of 2 m/s2 on the object. What is the mass of the object ?
Data:
F (force) = 5 N
m (mass) = ?
a (acceleration) = 2 m/s²
Solving:
Answer:
2.5 kg

The tendency for two masses alone in the universe to drift together is a result of gravitational pull.
