When traveling at top speed, a roller coaster train with a mass of 12,000 kg has a velocity of 30 m/s. The kinetic energy of the train at top speed is J. Given this kinetic energy, what is the tallest hill this roller coaster train can reach the top of? The train can climb a hill that is m high. pls help

Kinetic energy = 5400000 J

Height, h = 45.91 m

Explanation:

Method:

Mass of the roller coaster train, m = 12,000 kg

Velocity of the train, v = 30 m/s

Kinetic energy = 1/2mv^2 (^2 stands for square)

                         = 1/2 x 12000 x 30 ^2

                         = 5400000 J

For height

In general, as,

P.E + K.E = P.E + K.E

0 + 5400000 = mgh + 0

5400000 J = 12000 kg x 9.8 m/s x h

h = 45.91 m

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
