If bonds are broken, the energy is released, and if bonds are formed, energy is absorbed. During conversions from chemical energy to thermal energy, the energy stored in the chemical bonds are released and this energy causes surrounding molecules to move faster thus increasing the thermal energy of a substance.
Speed is the rate at which something covers a distance; velocity is the same but it takes into account whether it goes forwards or backwards; and acceleration is the rate of an increase in speed.

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>
