Calculate The Speed Of A Frictionless Rollercoaster

Question

A 1500kg roller coaster is at the top of a track and is travelling forward with a velocity of 1.0 m/s. It then goes down the track a distance along the track of 50m. The track is inclined at 50 degrees to the horizontal.

(a) If the track is frictionless, calculate the speed of the roller coaster at the bottom of the track.

(b) The speed of the roller coaster at the bottom is measured and is found to be 22.5 m/s. Explain this difference between the calculated and measured speed.

Summary

The question belongs to Physics and it is about calculating the speed of a frictionless rollercoaster.
