Answer:
If the speed of the object becomes double, its kinetic energy changes to four times the initial kinetic energy.
Example:
If Your Car is going 40MPH And The Kinetic Energy is lets just say 40 and you speed up to 80MPH and the kinetic energy stays at 40 your car would loose control but if the kinetic energy rises to 80 then the car would not lose control and you wouldnt have to worry

Answer:
0.304 m/s2
Explanation:
If the first child is pushing with a force of 69N to the right and the 2nd child is pushing with a force of 91N to the left. Then the net pushing force is 91 - 69 = 22 N to the left. Subtracted by 15N friction force then the system of interest is subjected to F = 7 N net force tot he left.
We can use Newton's 2nd law to calculate the net acceleration of the system
