A.) How fast is the coaster traveling at the bottom of the loop-de-loop. B.) Find the velocity of the coaster at the top of the loop-de-loop.
C.) Find the velocity at the end of the ride. (at 35 m)
D.) If a giant spring were placed at the end of the ride (35 m high), determine the spring constant necessary to stop the coaster in 1.8 m.
E.) If 60% of the original energy is lost due to friction, determine the velocity at the end. (35 m)

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
