Kinetic energy is movement, thus movement would be a characteristic that allows an object to have kinetic energy

Object A has of mass 7.20 kilograms, and object B has a mass of 5.75 kilograms. The two objects move along a straight line towar
Vera_Pavlovna [14]
If the collision is elastic, there is no loss in kinetic energies, which means that the total energies before and after impact are the same.  So no need to worry about final velocities.

Final energy
= initial energy
= (1/2) (7.20*2.00^2+5.75*(-1.30)^2)
=19.26 joules

Answer: the total kinetic energy is 19.3 J. after collision.

Annette [7]

Answer:

B

Explanation:

Let m be mass of the object and v be speed of object b.

Kinetic Energy of B = 1/2 mv^2

Kinetic Energy of A = 1/2 m(2v)^2

= 2 mv^2

= 4 (1/2 mv^2)

= 4 × Kinetic Energy of B

Hence Object A has four times the kinetic energy of object B (<em>A</em><em>n</em><em>s</em><em> </em><em>B</em><em>)</em>

A. a large amount of energy released into its surrounding

During the respiration, glucose molecules are converted to other molecules in a series of steps. They finally end up as as carbon-dioxide and water.

The overall reaction is

<span>C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + 2805 kJ
</span>
The reaction is exothermic reaction because <span>C=O and O-H bonds in the products are so much more stable than the bonds in the reactants.
</span>
Bond energy is the average needed to break a bond.

Some bond energies are:
C-C = 347 kJ/mol
C-H = 413kJ/mol;
C-O = 358 kJ/mol;
O-H = 467 kJ/mol;
O=O = 495 kJ/mol;
<span>C=O = 799 kJ/mol</span>
