Answer:
KE = 250 kg/m/s
Explanation:
use the formula: KE = 1/2 m (v^2)
KE = 1/2 (5) (10^2)
KE = (2.5) (100)
KE = 250 kg/m/s

Answer:
Box 1 has more mass than box 2.
Explanation:
Box 1 has more mass than box 2, as it caused a greater affect in the change of speed of box 2. During a collision, the object with a lesser mass will be affected more, causing the velocity to change more. Because box one is greater than box 2, it caused a larger change in speed when they collided.
It can never be shorter than a component - magnitude of a vector is the square root of the sum of the components squared, and a square function never produces a negative number. However, it can be the same size as it's component, if that component is the only one.
