If you need additional resources to support virtual learning, please ... 9) I can solve problems involving a system of linear inequalities. ... of the submarine is 50 ft below sea level when it starts to descend ... ft/s. It dives at that rate for 5 s. ... After the initial 5-second descent, the submarine increases its rate of ...
Step-by-step explanation:
The one all the way to the left matches with 1/7
1/18 matches with 0.05
0.5 matches with square root of 0.25
2/3 matches with 0.6
That's all I can help with.
4 x y x 4 x 2
the x I wrote stands for multiply
A= 72.5 (you take 145 and divide by 2 b/c one inside is smaller)
B= 72.5 also b/c the share a corresponding line
Magnitude of the momentum of this system just after the collision = 19.2Kgm/s
<h3>What is law of conservation of momentum?</h3>
Law of conservation of momentum states that the total momentum after the collision must be equal to the total momentum before the collision.
The momentum of each ball is given by:
p = mv
where m is the mass of the ball and v its velocity.
The momentum of ball 1 is:
p = mv
= (3.0 kg)(4.0 m/s)
= 12.0 kg m/s in the eastward direction
The momentum of ball 2 is:
p = mv
= (5.0 kg)(3.0 m/s)
= 15.0 kg m/s in the northward direction
The two momenta are in perpendicular directions, so the magnitude of the total momentum can be found as:
and due to the law of conservation of the momentum, this is also equal to the total momentum after the collision.
