Answer:
Explanation:
a. Given that:
mass of first & second piece, 
mass of 3rd piece,
-velocity of first piece(
) and 
as velocity of 2nd piece (
)
Let 
be velocity of 3rd piece=?
#Vessel is at rest before explosion. Considering conservation of linear momentum:
#Dividing both sides by 
#Plug the
values:
#So the magnitude of the third piece is:
Magnitude of the 3rd piece is 10.84 m/s
b. To find direction of the magnitude (as an angle relative to the 
-axis), we find 
. The angle is obtained by getting the tan inverse as:
-The direction of the magnitude (angle relative to the x-axis) is 45°
Answer:
evaporation to condensation to precipitation.
Multiply by (1000 meters / 1 km).
Then multiply by (1 hour / 3600 seconds).
Both of those fractions are equal to ' 1 ', because the top
and bottom numbers are equal, so the multiplications
won't change the VALUE of the 72 km/hr. They'll only
change the units.
(72 km/hour) · (1000 meters / 1 km) · (1 hour / 3600 seconds)
= (72 · 1000 / 3600) (km·meter·hour / hour·km·second)
= 20 meter/second
The process of preparing a person to perform strenuous work and to recover from that work as quickly as possible is called training, I bet. Such w<span>arm up exercises as like stretching and other should lead person to the recovery. Hope it will help.</span>
