The velocity of a wave is primarily determined by the
1 answer:
<h2>Answer: medium </h2><h2 />
The propagation velocity of a wave depends on the medium in which it propagates.
In addition, it depends on the type of wave, for example a mechanical or electromagnetic wave.
In any case, the velocity of a wave is generally related to the value of the wavelength and the period, and can be expressed mathematically through the following formula:
where is the velocity of the wave,
is the wavelength and
is the period.
Therefore:

2.71 m/s fast Hans is moving after the collision.
<u>Explanation</u>:
Given that,
Mass of Jeremy is 120 kg ()
Speed of Jeremy is 3 m/s ()
Speed of Jeremy after collision is () -2.5 m/s
Mass of Hans is 140 kg ()
Speed of Hans is -2 m/s ()
Speed of Hans after collision is ()
Linear momentum is defined as “mass time’s speed of the vehicle”. Linear momentum before the collision of Jeremy and Hans is
=
Substitute the given values,
= 120 × 3 + 140 × (-2)
= 360 + (-280)
= 80 kg m/s
Linear momentum after the collision of Jeremy and Hans is
=
= 120 × (-2.5) + 140 ×
= -300 + 140 ×
We know that conservation of liner momentum,
Linear momentum before the collision = Linear momentum after the collision
80 = -300 + 140 ×
80 + 300 = 140 ×
380 = 140 ×
380/140=
= 2.71 m/s
2.71 m/s fast Hans is moving after the collision.
