Answer:
the magnitude of the momentum of the two-ball system immediately after collision is 32.31 kg.m/s
Explanation:
Given;
mass of the first ball, m₁ = 1.0 kg
mass of the second ball, m₂ = 2.0 kg
initial velocity of the first ball, v₁ = 30 m/s due west
initial velocity of the second ball, v₂ = 6 m/s due north
From the principle of conservation of linear momentum;
the total momentum before collision = total momentum after collision
The westward momentum of the first ball, = m₁v₁ = 1 x 30 = 30 kg.m/s
The northward momentum of the second ball = m₂v₂ = 2 x 6 = 12 kg.m/s
The resultant momentum of the two balls;
R² = 30² + 12²
R² = 1044
R = √1044
R = 32.31 kg.m/s
Therefore, the magnitude of the momentum of the two-ball system immediately after collision is 32.31 kg.m/s

Part a).
You said that 1,609 meters = 5,280 feet
We know that 1 meter = 100 centimeters, and 1 foot = 12 inches.
So (1,609 meters) x (100 centimeters/meter) = (5,280 feet) x (12 inches/foot)
The second fraction on each side of the equation is equal to ' 1 ', because
the numerator is equal to the denominator, so sticking it in there doesn't
change the value of that side of the equation. But now we can cancel some
units,and wind up with the units we need.
(1,609 meters) x (100 centimeters/meter) = (5,280 feet) x (12 inches/foot)
(1,609 x100) centimeters = (5,280 x 12) inches
160,900 centimeters = 63,360 inches
Divide each side by 63,360 : <em> 2.54 centimeters = 1 inch</em>

part b).
I haven't seen the snail, or anything else in problem 7,
so there's no way I can answer this part.
B. Is the answer explanation: if not you need help me or you can sleep over here every day so that you don’t know where you can
Explanation:
It is based upon the fact that " The light travels faster then sound." As the speed of light is faster then the speed of sound, light travels 300,000 km per second and sound travels 1192 km per hour. That is why we observe the lightening first and hear the the sound of thunder later.
You can do this experiment by yourself. Once you see the lightening start counting the seconds until you hear the sound of thunder.Then divide the seconds by 5, you will find out how many miles away the lightening strike was.
