Temperature is a measure of of the particles in an object.
a. the difference between the potential and kinetic energy
b. the sum of the potential and kinetic energy
c. the average potential energy
d. the average kinetic energy

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.

because if the tool that you are using is not balanced it there would be false mass.

answer(20) psi;
