How does using a simple machine give mechanical advantage?

Question 3 options:

Simple machines use electricity

It trades distance for a more efficient use of force to do work

Only complex machines give mechanical advantage

Simple machines automatically complete tasks for you

Question: The super hero known as the Flash, who's mass is 60 kg, runs toward the fire at a speed of 100 m/s. What is the Flashes Kinetic Energy?

STEP 1: What is the unknown (what is the question asking for?)

Question 6 options:

Kinetic Energy (J)

Force (N)

Work (J)

Potential Energy (J)

Question: The super hero known as the Flash, who's mass is 60 kg, runs toward the fire at a speed of 100 m/s. What is the Flashes Kinetic Energy?

STEP 1: What is the Known information (information given in the question)

Question 7 options:

Mass = 60 kg and Distance = 100 m

Distance = 60 kg and Mass = 100 m/s

Weight = 60 kg and Acceleration is 100 m/s

Mass = 60 kg and Velocity is 100 m/s toward the fire

Question: The super hero known as the Flash, who's mass is 60 kg, runs toward the fire at a speed of 100 m/s. What is the Flashes Kinetic Energy?

STEP 3: What is the Equation needed

Question 8 options:

KE=12mv2

PE=mgh

W=F*d

KE=−ΔPE

Question: The super hero known as the Flash, who's mass is 60 kg, runs toward the fire at a speed of 100 m/s. What is the Flashes Kinetic Energy?

Step 4: SOLVE

Step 5: Check

Question 9 options:

300,000 J

6,000 J

3,000 J

1.667 J

ANSWER AS MUCH AS YOU CAN IF YOU KNOW ALL OF THEM ANSWER ALL OF THEM.

The mechanical advantage increases as the slope of the incline decreases. But the load will then have to be moved a greater distance. The ideal mechanical advantage (IMA) of an inclined plane is the length of the incline divided by the vertical rise, the so-called run-to-rise ratio.
