The final velocity of the 1.4 kg ball is 11.0 m/s to the right
Explanation:
We can solve this problem, by using the law of conservation of momentum: in fact, the total momentum of the two balls must be conserved before and after the collision. Therefore, we can write:
where:
is the mass of the first ball
is the initial velocity of the first ball (taking right as positive direction)
is the final velocity of the first ball
is the mass of the second ball
is the initial velocity of the second ball (it is at rest)
is the final velocity of the second ball
And solving the equation for v2, we find:
So, the 1.4 kg ball moves at 11.0 m/s to the right.

Answer:
Speed of light = 3 * 10 ^8 m / s. Speed is related to the distance and time and so its unit is in meters and seconds. The speed of light value mentioned above is the value calculated in vacuum or air with the help of lasers.
But when it comes to water, refractive index has to be taken into account.The speed of light is faster in vacuum than other mediums.
an armature
a solenoid
a battery
the answer is a battery
