The correct option is B.
Matter is defined as anything that has mass and occupy space. The kinetic theory of matter states that all matters are made up of huge number of small particles which are in constant motion. These small particles are called atoms. Each atom has sub particles, which are electrons, protons and neutrons. The electrons are in constant motion orbiting the nucleus in which the protons and the neutrons are located. The electrons are able to move about constantly because they possess energy.
Answer:
by using v = u + at equation we can find "a"
14 = 60 - 2.7a
2.7a = 60 - 14
2.7a = 46
decceleration = 17.03
