Physics, Net force and Acceleration

Click For Summary
A 4.0 x 10^1 kg wind sled is initially moving at a constant speed of 12 m/s when a gust of wind exerts a force of 1.0 x 10^2 N for 3.0 seconds. The relevant equations include Newton's second law (F = ma) to determine acceleration and the kinematic equation to find the final velocity. The sled experiences an acceleration of 2.5 m/s² due to the wind force, resulting in a velocity increase over the 3 seconds. After the wind subsides, the sled's final velocity is calculated to be 22.5 m/s. This analysis demonstrates the impact of external forces on an object's motion.

A 4.0 x 101 kg wind sled is gliding East across a frozen lake at a constant speed of 12 m/s,
when a gust of wind from the southwest exerts a constant force of 1.0 x 102 N on its sails
for 3.0 s. With what velocity will the sled be moving after the wind has subsided?

Thread 'Correct statement about size of wire to produce larger extension'

The answer is (B) but I don't really understand why. Based on formula of Young Modulus: $$x=\frac{FL}{AE}$$ The second wire made of the same material so it means they have same Young Modulus. Larger extension means larger value of ##x## so to get larger value of ##x## we can increase ##F## and ##L## and decrease ##A## I am not sure whether there is change in ##F## for first and second wire so I will just assume ##F## does not change. It leaves (B) and (C) as possible options so why is (C)...
