Answer:
Math Skills Calculating Kinetic Energy and Potential Energy ... moving object depends on its mass and speed. ... represents the object's speed, measured in meters per second (m/s). ... Example 1: A bicycle and rider with a combined mass of ... the bicycle and rider? Given: m = 110 kg v = 8 m/s. Unknown: Kinetic energy (KE).
I think
Explanation:
Answer: Because a house is likely to increase in price while automobiles and refrigerators are less likely to gain in value.
Explanation: bubbles usually come from soap soooo.... why would they sell it with automobiles?...lol
Choices 1,3,4 are supported.
Choice 2 is incorrect because a horizontal slope on a position time graph means the object is starionary.
Choice 5 is incorrect because the speed of an individual can be determined by calculating the slope at a point on the position time graph.
Answer:
h=4r
Explanation:
To solve the problem it is necessary to apply the energy conservation equations for the roller coaster.
The energy conservation equations warn that:
Where,
Kinetic Energy
Potential Energy
Equating,
Re-arrange for V,
For balance of forces, according to the announcement, those who are on a roller coaster can withstand up to a maximum of 9g.
Therefore, considering the centripede speed and the speed of the fall, we obtain that,
The centripetal acceleration is given by the equation
Where
V = Tangencial velocity
r = Radius
Then replacing in the equation of Force,
Therefore the maximum height of the incline if the cars starts from the rest is 4 times the raidus of the inclination
