The formula for working out kinetic energy is
=122
KE = kinetic energy
m = mass of a body
v = velocity of a body
kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.
For the first one I think :
Answer:
KE = 330750 J
I’m not sure about the second one- sorry
The third is
Answer:
KE = 41454 J
Hope it helps and it is correct, sorry if it isn’t !

Answer:Displacement</h2>
Explanation:
Potential energy is present in a spring because the spring is elongated and some work is done it to elongate it.
The elastic potential energy present in a spring is given by 
where 
is the spring constant.It may vary from spring to spring and 
is the displacement of the spring from its equalibrium position.
It is evident from the equation that potential energy in the spring increases as 
increases.
400 divided by 8 is 50, so its acceleration is 50 knots per second, meaning its speed is increasing by 50 every second.
After the second car starts out,
D = 30 + 110 H
360 = 30 + 110 H
330 = 110 H
H = 330/110
H = 3 hours after the second car leaves.
That's 3.5 hours after the first car leaves.
