Answer:
The speed of the vehicle was 21 m/s
Explanation:
Momentum can be defined as mass in motion
Momentum depends on the variables mass and velocity
The momentum of an object is equal to the mass of the object times the
velocity of the object
The given is:
→ A Jeep Rubicon has a mass of 2,630 kg
→ With a momentum of 55,200 kg m/s
We need to find the speed of the vehicle
→ The momentum = mass × speed
Substitute the values above in the rule
→ 55,200 = 2,630 × speed
Divide both sides by 2,630
→ speed = 20.99 ≅ 21 m/s
<em>The speed of the vehicle was 21 m/s</em>
You can picture a sound wave a lot like a Slinky wave . . . a
thicker, compressed blob moving along the path, with thinner,
stretched-out places before and after it.
The thicker parts of a sound wave, where the air is more dense,
are called compressions.
The thinner parts of a sound wave, where the air is less dense,
are called rarefactions.
Answer:
The mass is 
Explanation:
Generally from Newton law for the first block
=>
For the second block the force is
and the acceleration is 
So from Newton law
=> 
substituting for a
=> 
=>
