What factors affect the amount of potential and kinetic energy a roller coaster has

Physics
1 answer:
Svetlanka [38]3 years ago
3 0

Answer:

As the roller coaster goes higher, more potential energy is increased in the roller coaster. Caused by gravity and the roller coaster's position, the potential energy is stored in the roller coaster. For example, this ball is at the top of a hill, where potential energy is at it's highest. Potential energy can be calculated by Potential Energy=Mass X Acceleration X Height.

A few years ago, the legal speed limit on the Turner Turnpike was changed from 55.0 mi/h to 75.0 mi/h.

The amount of time saved on the 86.0 mile trip from Tulsa entrance to Oklahoma City is 0.42 hours

<h3>What is time?</h3>

Time is the measurement of a past, present, or future event. The S.I unit of time is seconds (s)

To get the time that was saved on the 8.6-mile trip, we use the formula below.

Formula:

  • Ts = (d/v₁)-(d/v₂)................. Equation 1.

Where:

  • Ts = Time saved on the trip
  • d = distance covered during the trip
  • v₁ = Initial legal speed limit
  • v₂ = final/current legal speed limit.

From the question,

Given:

  • d = 86.0 mile
  • v₁ = 55.0 mi/h
  • v₂ = 75.0 mi/h

Substitute these values into equation 1

  • Ts = (86/55)-(86/75)
  • Ts = 1.564-1.147
  • Ts = 0.42 h.

Hence, The amount of time saved on the 86.0 mile trip from Tulsa entrance to Oklahoma City is 0.42 hours.
