Determine the gross force (in N) needed to bring a car that is traveling at 105 km/h to a full stop in a distance of 150 m. The mass of the car is 2,100 kg. (Enter the magnitude.) N What happens to the initial kinetic energy? Where does it go or to what form of energy does the kinetic energy convert? O The kinetic energy changes into thermal energy. O The kinetic energy changes into elastic energy. O The kinetic energy changes into potential energy. O The kinetic energy does not change. O The kinetic energy is destroyed.

Unit Conversion

Standard units are also called SI units. SI units are used for measuring a physical quantity satisfying certain conditions. There are two types of units: fundamental units and derived units. Fundamental units are physical quantities that are independent, that is, they do not depend on other quantities like mass, length, or time. There are plenty of quantities in our lives which need to be measured and compared. Measuring is the comparison of a particular physical quantity with its reference value. A unit is a measure of a fixed physical quantity. A physical quantity is the product of a unit and the numerical value we need to compare with.
