Answer :
Answer:
Explanation:
Consider the KE formula.
KE = 1/2 m v^2
If you double the speed, it get's squared. m should stay the same.
suppose m = 10 and v = 5
KE = 1/2 * 10 * 5^2
KE = 1/2 * 10 * 25
KE = 5 * 25
KE = 125
Now don't change the m and make v = 10
KE = 1/2 * 10 * 10^2
KE = 5 * 10^2
KE = 5 * 100
KE = 500
If you multiply 4 * 125 you get 500
D o notice that doubling the speed increases the KE by 4?
