Where
m is the mass
v is the speed of the object
Car A has twice the mass of Car B. Both travel at the same speed i.e.

So,

So, the kinetic energy of car A is twice of the kinetic energy of car B.

Answer:
4×10⁴ seconds
Explanation:
Assuming you have a calculator on hand, inputting 300 ÷ .0081 give should give you 37037.0370...
In scientific notation, that number would be 3.70370370...×10⁴ and when taking into account the rounding rules for significant figures, the answer is 4×10⁴ seconds.
