Explanation:
It is given that,
Speed of an automobile is 25 km/h or 6.95 m/s
Kinetic energy of the automobile is 
(a) Kinetic energy of automobile s given by :
(b) If the velocity of the car is increased to 45 km/hour or 12.5 m/s, new kinetic energy becomes :
(c) If the velocity is increased to 80 km/hour, 22.23 m/s, So
Hence, this is the required solution.

Answer: E = 5.004*10^(20) joules
Explanation:
We do not have a lot of information about the impact, so we can assume that the energy released on the impact was the kinetic energy of the large fragment.
Remember that the kinetic energy of an object of mass M that moves at a velocity V is:
K = (M/2)*V^2
in this case, we know that the speed (that is equivalent to the velocity) is:
V = 60,000 m/s
And the mass is:
M = 1.39*10^(11) kg
Then the kinetic energy of the large fragment was:
K = (1.39*10^(11) kg/2)*( 60,000 m/s)^2 = 5.004*10^(20) joules.
Then we could conclude that the energy released on the impact was:
E = 5.004*10^(20) joules
