A Truck Has Four Times the Mass of a Car $K _ { \mathrm { t } } \text { and } K _ { \mathrm { c } }$

A truck has four times the mass of a car and is moving with twice the speed of the car. If $K _ { \mathrm { t } } \text { and } K _ { \mathrm { c } }$ refer to the kinetic energies of truck and car respectively, it is correct to say that

A) $K _ { \mathrm { t } } = 16 K _ { \mathrm { C } }$
B) $K _ { \mathrm { t } } = 2 K _ { \mathrm { C } }$
C) $K _ { \mathrm { t } } = K _ { \mathrm { C } }$
D) $K _ { \mathrm { t } } = \frac { 1 } { 2 } K \mathrm { c }$
E) $K _ { \mathrm { t } } = 4 K _ { \mathrm { C } }$
