This problem can be solved through the Inelastic Collision Formula:
mass1 x in.velocity1 + mass2 x in.velocity2 = mass1+mass2 (final velocity)
Substituting the values, we have:
0.40 kg x in.velocity1 + 0.40 kg x 0 m/s = 0.80 kg (8.0m/s)
Solving for the unknown initial velocity of the moving hockey puck we have:
in.velocity1 = (6.4 kgm/s - 0) / 0.40 kg
= 16 m/s
Answer:
The entire rainbow of radiation observable to the human eye only makes up a tiny portion of the electromagnetic spectrum – about 0.0035 percent. This range of wavelengths is known as visible light.

Hi! ^-^
At what age is a child likely to learn to sit up without support?
I would say Five months if you position the child but Nine months for the baby to sit up by themselves! So the answer is Nine months!
Have a BEAUTIFUL day~
Gravitational potential energy :)
Answer:
The tendeny of a body to continue its state either motion or rest is called inertia . First law of newton also called law of inertia .
There are three types of inertia
1. Motion inertia
2. Rest inertia
3. Directional inertia
