ceday said:Is the net force in the y direction zero?
does the centripetal force = 2mg since normal and gravity both point downward?
im lost since this coaster is upside down
ceday said:ok, i got the answer but i used the net force=2mg
i still don't understand why this is so
The speed of a roller coaster car at the top of a loop-the-loop is calculated using the conservation of energy principle. This means that the potential energy at the top of the loop, which is determined by the car's height and mass, is equal to the kinetic energy at the bottom of the loop, which is determined by the car's velocity.
The speed of a roller coaster car at the top of a loop-the-loop is affected by the car's mass, the height of the loop, and the gravitational pull of the Earth. The shape and design of the loop can also impact the car's speed.
Yes, the speed of a roller coaster car at the top of a loop-the-loop can be greater than its initial speed. This is due to the car's potential energy being converted into kinetic energy as it travels through the loop.
The speed of a roller coaster car at the top of a loop-the-loop can greatly impact the ride experience. A higher speed can create a more intense and thrilling experience, while a slower speed may result in a less exciting ride.
Yes, there is a maximum speed that a roller coaster car can reach at the top of a loop-the-loop. This is determined by the car's mass, the height of the loop, and the gravitational pull of the Earth. If the car reaches a speed that is too high, it may not be able to complete the loop and could potentially derail.
