Answer:
- The x-component of the velocity of the third particle is
- The y-component of the velocity of the third particle is
- The increase in kinetic energy is
Explanation:
We can take conservation of linear momentum to find the velocities:
The initial momentum of the nucleus will be:
as is at rest.
After the decay, the first particle has a momentum
the second one has a momentum
By conservation of linear momentum we have:
for the third particle, we know that mass is conserved:
The velocity will be:
The kinetic energy is given by
And, as the initial kinetic energy is zero, this must be the increase in energy.
You can write an hypothesis such as this:
The weight of an object has effects on the operating frictional force, the greater the weight, the higher the operating frictional force.
The father is the one with the higher weight while the son has the lower weight. The operating frictional force is the friction that their weights exert.
Answer:
in accelerated motion
Explanation: tbh I just guessed if im wrong sorry
Answer: His weight plus the centripetal force must equal 1170 N
Explanation:
83.0 [g + (v^2 / r)] = 1170
v^2 / 18.0 = (1170 / 83.0) - 9.81
