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)

The geological theory that states that pieces of earth's lithosphere are in constant slow motion is the theory of plate tectonics.

Answertechnician (a) is correct;

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !
