Usually what people mean by that is that life is full of ups and downs. ... You get on the roller coaster for the "downs" not the "ups"! That's not trivial. Because the "downs" are where all the fun & thrill is.
12. what type of force is shown when riding a roller coastewhat type of force is shown when riding a roller coaster?
Answer:
Gravity
Explanation:
basta gravity sagot sureness yan
Answer:
At every point on a roller coaster ride, gravity is pulling you straight down. The other force acting on you is acceleration. When you are riding in a coaster car that is traveling at a constant speed, you only feel the downward force of gravity.
13. what is roller setting?
Answer:
Also known as a "roller set" or a "wash and set," a wet set can either create curls or straighten hair, depending on the tools you decide to use. Rollers of various sizes are often used to curl the hair slightly, or create a gentle curl or "bump" on the ends while providing volume.

15. A roller coaster is pulled up a hill by a chain attached to a motor . The roller coaster has total mass of 15,000kg.If it takes 30 seconds to pull the roller coaster up a 40 meter Hill. how powerful is the motor?
Answer:
The free-body diagram (part a) is shown at the right.
The acceleration of the car can be computed as follows:
a = v2/R = (18.0 m/s)2/(12.0 m) = 27.0 m/s2 (part b)
The net force can be found in the usual manner:
Fnet = m•a = (500. kg)•(27.0 m/s2) = 13500 N (part b)

Answer:
162324.49
Step-by-step explanation:
162162162 ÷ 999
= 162324.486486
#Answerfortrees
Answer:
= 162,325 passengers per minuteStep-by-step explanation:
To get the rate of x passengers per minute, just divide the total number of passengers by the total number of minutes.
162,162,162 passengers ÷ 999 minutes
= 162,325 passengers per minute

22. how does the roller move compared with results in step 2 determine the acceleration of the roller compare this a?
When we compare rolling friction and sliding friction, the first thing we notice is that the energy loss in rolling is much lesser compared to sliding (about 2-3 orders of magnitude lesser), provided the bodies considered are reasonably rigid.

25. a 1000kg roller coaster car is moving with a speed of 20m/s,The roller coaster has kinetic energy.Calculate it.
Answer:
200,000 J
Given:
m=1000kg
v=20m/s
Formula and Solution:
KE = ½mv²
= ½•1000•20²
= 500•400
KE = 200,000 J
