When traveling at top speed, a roller coaster train with a mass of12,000 kg has a velocity of 30 m/s. the kinetic energy of the train at top speed is

The kinetic energy of the train at top speed is 5,400,000 J

Explanation:

Kinetic Energy

It's the capacity that an object has to do work in virtue of its velocity. If we use UI units for the mass and velocity, the kinetic energy is expressed in Joules, or Nw.m or . It can be computed with the formula

The roller coaster train has a mass of 12,000 kg and a velocity of 30 m/s. Replacing those values in the formula, we have:

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).

connectedness in handwriting analysis is a useful tool in establishing the writer’s method of thinking and its perception in where he/she fits in to the environment around him in the social sense. in addition, the more connected the writing of an individual, the more he/she is flexible and single minded.
