If the roller coaster is moving, it will want to keep moving, along the direction of motion, unless something causes it to speed up or slow down. This resistance of the moving roller coaster to changing its velocity is another example of its inertia. Again, the greater the mass of the body, the more inertia it has.
<span>The magnitude of an object's average velocity is equal to its
average speed during the same period of time, when the distance
it covers is equal to its displacement during that time.
This happens when the object travels in a straight line.</span>
Take 771.9 Kg M/s because that's how fast she is moving and divide it by 93 kg because that is her force pushing down
771.9/93= 8.3
Answer: A. 8.3 M/s
P.s I changed my answer on the last question you asked so change that.
The correct answer should be polygenic inheritance
Most genes that affect the way a human being looks have been inherited in this way. Not only hair but also things like height and weight, eye color, and similar.
Answer:
I will answer this in English.
He has 45 years.
a year has 365 days.
a day has 24 hours.
So he has:
45*365*24 hours = 394,200 hours.
His mass is 78 kg,
And we know that 1 slug = 1lbf*ft/s^2
Then, the first step is transform the 78 kg into lbf.
1kg = 2.2 lbf.
then 78kg = 78*2.2 lbf = 171.6lbf.
Now, the weight is m*g, where m is the mass and g is the gravitational acceleration, in this case the gravitational acceleration in ft/s^2 is:
g = 32.2 ft/s^2
Then the weight in slugs is:
W = 32.2ft/s^2*171.6lbf = 5,525.5 slugs
