Kinetic energy = 1/2Mass x Velocity^2
KE = 1/2(1990) x (28^2)
KE = 995 x 784
KE = 780080 Joules
Kinetic energy
There are two factors that determine and object's kinetic energy. The two main factors are mass and velocity.
That depends on the weight of the vehicle(s) and how fast it (they) are travelling.
-- mass of the vehicle -- speed of the vehicle
Mass, speed.
Kinetic energy
Kinetic energy is extra energy resultant of motion. So, a moving vehicle has kinetic energy.
The kinetic energy of a vehicle, of mass m kilograms and travelling at velocity v metres per second, is 1/2*m*v2.Using calculus, d(ke)/dv = m*v.That is, the kinetic energy (ke) increases by the product of the mass and the velocity. Whether or not that can be considered "tremendous" is another matter.The kinetic energy of a vehicle, of mass m kilograms and travelling at velocity v metres per second, is 1/2*m*v2.Using calculus, d(ke)/dv = m*v.That is, the kinetic energy (ke) increases by the product of the mass and the velocity.

Look at the equation for kinetic energy. It clearly shows that the kinetic energy depends on the object's mass, and its speed.

YES ... When a car is moving, it has kinetic energy. If you apply the brakes, the vehicle will slow down and thus loose some of that kinetic energy. The energy that was kinetic from the fast moving vehicle is transferred into heat energy in the braking mechanism (the rotor disks and pads.)
The kinetic energy of the vehicle when it is travelling faster is four times as great. It the brakes apply the same retardation and the friction from the tires on the road surface is unchanged then the stopping time will be four times as long.
No, unless it is moving (e.g. you threw it, it is in a moving vehicle). Only moving objects have kinetic energy.
That depends on the weight of the vehicle(s) and how fast it (they) are travelling.
If you are refering to the 'sound' that music produces, that's kinetic energy of the sound waves travelling though air.
The kinetic energy of an object varies as the square of its velocity (Kinetic energy = mv2/2). So a plane with the same mass travelling at 3 times the velocity will have 9 times the kinetic energy.
