1. A 20 kg object is thrown with an initial upward velocity of 2 m/s. If air resists motion of the object by 4 N for each m/s, w

dlinn [17]

Answer:

49 m/s

Step-by-step explanation:

We don't know what your model is, so we'll solve this based on the balance of forces. Air resistance exerts an upward force of ...

(4 N/(m/s))v

Gravity exerts a downward force of ...

(20 kg)(9.8 m/s²) = 196 N

These are balanced (no net acceleration) when ...

(4 N/(m/s))v = 196 N

v = (196 N)/(4 N/(m/s)) = 49 m/s

The terminal velocity is expected to be 49 m/s.

Marcia bought a bag of red white and blue balloons for the party there were 49 balloons in the bag if there are twice as many re

DedPeter [7]

Answer:

Red color= 28 balloon

Blue color= 14 balloon

White color= 7 balloon

Step-by-step explanation:

Given: There are 49 balloons

As given, there are 2 red balloon equal to the number of blue balloon

∴ $2 red= blue\ balloon$

Again given, there are 1/2 white balloon equal to the number of blue balloon.

∴ $\frac{1}{2} \ white= blue\ balloon$

As above equation, we can understand that:

$2\ red= \frac{1}{2} \ white\ balloon$

multiplying both side by 2

⇒ $4\ red= white\ balloon$

which mean, if we have 2 blue balloon then we will have 4 red and 1 white balloon.

∴ Total combination of all color of balloon= $2+4+1= 7$

Now, checking how many number of times combination can we have in 49 balloon.

$\frac{49}{7}= 7 \ times$

Next, finding number of balloon in each color.

Red color= $4\times 7= 28\ balloon$

Blues color= $2\times 7= 14\ balloon$

White color= $1\times 7= 7\ balloon$
