Cognitive:
This is because teens tend to excrete more hormones when they are in their adolescent ages causing them to act in a riskier behavior.
Emotions:
Because of their feeling that they want to have freedom.
Physical:
Their hormones are affecting their actions.
´To develop this problem we will use the concepts related to the conservation of momentum and the application of energy conservation equations to find the velocity of the mass after the collision, like this:
Velocity of the mass
just before the collision



Therefore the momentum just before collision would be

Momentum after the collision

Since the momentum is conserved we have that



The velocity of mass
after the collision is given by



Therefore the change in momentum of mass 2 is



Therefore the impulse acting on m2 during the collision between the two boxes is 
Explanation:
Taking west to be positive, given:
v = 17.9 m/s
a = 63.7 m/s²
t = 0.21 s
Find: v₀
v = at + v₀
17.9 m/s = (63.7 m/s²) (0.21 s) + v₀
v₀ = 4.52 m/s
The initial velocity is 4.52 m/s west.
Answer:
d = 265 ft
Therefore, an object fall 265 ft in the first ten seconds after being dropped
Explanation:
This scenario can be represented by an arithmetic progression AP.
nth term = a + nd
Where a is the first term given as 2.63 ft.
d is the common difference and is given as 5.3ft.
n is the particular second/time.
To calculate how far the object would fall in the first 10 seconds, we can derive it using the sum of an AP.
d = nth sum = (n/2)(2a+(n-1)d)
Where n = 10 seconds
a = 2.65 ft
d = 5.3 ft
Substituting the values we have;
d = (10/2)(2×2.65 + (10-1)5.3)
d = 265 ft
Therefore, an object fall 265 ft in the first ten seconds after being dropped
