Answer the following regarding Momentum Change and Force

Mathematics
1 answer:

6 0

1. The force necessary to gain a velocity of 60 m/s within 5 mins is 40 N

2. The velocity gained by the object at the end of the second minute is 30 m/s

<h3>1. How to determine the force</h3>
  • Initial velocity (u) = 0 m/s
  • Final velocity (v) = 60 m/s
  • Mass (m) = 200 Kg
  • Time (t) = 5 ms = 5 mins = 5 × 60 = 300 s
  • Force (F) =?

F = m(v –u) / t

F = 200(60 – 0) / 300

F = 40 N

<h3>2. How to determine the velocity </h3>
  • Force (F) = 150 N
  • Mass (m) = 600 Kg
  • Initial velocity (u) = 0 m/s
  • Time (t) = 5 ms = 2 mins = 2 × 60 = 120 s
  • Final velocity (v) = ?

F = m(v –u) / t

Cross multiply

m(v –u) = Ft

Divide both sides by m

v - u = Ft / m

v - 0 = (150 × 120) / 600

v = 30 m/s

Pedro has a bag of flour that weighs 9/10 pound. he uses 2/3 of the bag to make gravy. how many pounds of flour does pedro use t
BARSIC [14]
Here is the solution of the given problem above.
First, let's analyze the question. 
Given: 1 bag = 9/10 pound
            2/3 bag = ? pound
What we are going to do is to divide 9/10 pound to 3.
so 9/10 divided by 3 and we get 9/30 and to simplify that, 3/10.
So per 1/3 of the bag, there is 3/10 pound. 
To get the weight for 2/3 of the bag, we multiply 3/10 by 2 and we get 6/10 or to simplify it, it is 3/5. Therefore, the 2/3 bag weights 3/5 pound. Hope this answer helps.

In the figure below, the value of x is:<br> who ever show works gets brainlly
blondinia [14]

Answer:

d)  x  = 72°

Step-by-step explanation:

Corresponding Angles:   The pair of angles formed on the same side of traversal which crosses two parallel lines is called a pair of corresponding angles.

These angles are EQUAL to each other.

Now, here in the given figure:

The two below lines are parallel to each other.

Also, the line crossing it on the right side forms a traversal.

So angle x and angle with 72 degrees form a pair of Corresponding Angles.

⇒ x  = 72°

Hence the measure of angle x  = 72°
