What is the car's speed at the bottom of the dip? the passengers in a roller coaster car feel 50% heavier thantheir true weight as the car goes through a dip with a 40.0 radius of curvature.

v = 14 m/s

Explanation:

given,

radius of dip = 40 m

The passengers in a roller coaster car feel 50% heavier than their true weight.

Apparent weight

When the car is at the bottom,  the weight will be acting downwards and the centripetal force will also be acting downward where as Normal force which is apparent weight will be acting in upward direction.

now,

v = 14 m/s

the gas collects in coils that then becomes a liquid that then flows through the coils inside the refrigerator
