Answer:
To identify the momentum of object 1, you must multiply mass (m) and velocity(v) to find momentum.
Object 1 has momentum of 8 kg. m/s before collision.
Object 1 has momentum of 0 kg. m/s before collision.
The combined mass after the collision had a total momentum of 8 kg. m/s.
Explanation:
Momentum of the object is given by,
Momentum = mass × velocity
For object 1:
Momentum = mass × velocity
Momentum = 2 × 4
Momentum = 8 kg. m/s
For object 2:
Momentum = mass × velocity
Momentum = 6 × 0
Momentum = 0 kg. m/s
For object 1 + object 2:
Momentum = mass × velocity
Momentum = 8 × 1
Momentum = 8 kg. m/s
To identify the momentum of object 1, you must multiply mass (m) and velocity(v) to find momentum.
Object 1 has momentum of 8 kg. m/s before collision.
Object 1 has momentum of 0 kg. m/s before collision.
The combined mass after the collision had a total momentum of 8 kg. m/s.
<u>Answer:</u>
The time taken for the ball to hit the floor as 1.02 seconds
<u>Explanation:</u>
As per the given question, the ball leaves at a speed from the table with an initial velocity of 10 m/s, we have the equation

where Vf represents the final velocity
Vi represents the initial velocity
a represents the acceleration and
t represents the time
after rearranging

= 1.022 seconds
True, the wavelength dies down due to high frequency and low amptitude.
It depends on where the sun and earth is.

i don't know what symbol ya'll use for wavelength so i just put the word instead.We use the greek symbol lambda.So just plug in everything you know.
wavelength=4.257×10^-7x10^-2 and
v=speed of light = 3×10^8
So you should get f= 7.04 ×10^15Hz
