Answer:

30 m/s

Explanation:

Vf = ?

Vi = 0 m/s

a = 20 m/s^2

t = 1.5 s

Plug those values into the equation: Vf = Vi + at

Vf = 0 + (20)(1.5)

Vf = 30 m/s

My answers would be as follows:

<span>You step on the scale and notice that you have lost five pounds. Which of the following has changed?


B) Only your weight changed since mass is conserved. It cannot be destroyed or created.


How could you increase the mass of a wooden block?

D) None of the above. Mass cannot be created so the mass will stay the same it will only be the weight you can increase depending on the acceleration.


If you went to the moon, how would your mass change relative to your mass on Earth?

A) It would be the same on the moon as on Earth. Mass will be the same. It is weight that will change since the gravitational acceleration in the moon is different as that to the earth.

the skid marks left by the decelerating jet-powered car the spirit of america were 9600 m long before it came to a stop at 198 m
N76 [4]

Answer:

97 s

Explanation:

Given:

Δx = 9600 m

v₀ = 198 m/s

v = 0 m/s

Find: t

Δx = ½ (v + v₀) t

9600 m = ½ (0 m/s + 198 m/s) t

t = 97 s

You are In-line skates at the top of a small hill. Your potential energy is equal to 1000 J. The last time we checked, your mass
stira [4]

A) <u>Weight = mass × acceleration (due to gravity)  </u>

= 60×9.8  

= 588 N  

<u>B) Potential energy = mass x gravity x change in height </u>

1,000 = 60.0 x 9.8 x h

h =  1.7 m      

<u>C) Kinetic energyF = potential energyI </u>

KEF = 1/2mv2  

PEI = mgh = 1,000 J

1/2mv2 = 1,000

1/2(60.0)v2 = 1,000  

v2 = 33.33

v = 5.77 m/s

Which client body temperatures are indicative of moderate hypothermia? select all that apply. one, some, or all responses may be
Lyrx [107]

The correct option is (3)  88° F (31.1° C) and (4) 92° F (33.3° C).

A medical emergency known as hypothermia happens when your body results in a dangerously low body temperature.

What is Hypothermia?

  • After being exposed to chilly, rainy, or windy environments, hypothermia develops.
  • Your body eventually exhausts its reserves of energy after prolonged exposure to cold temperatures, which causes your body temperature to drop.
  • When the body's temperature falls below 95° F (35° C), hypothermia sets in. The average body temperature is 37° C (98.6° F).
  • A medical emergency is hypothermia. The brain and body cannot operate normally when a person's body temperature is dangerously low. Hypothermia can cause cardiac arrest (heart stops beating) and death if it is not addressed.
