Answer:
F₁ / F₂ = 10
therefore the first out is 10 times greater than the second barrier
Explanation:
For this exercise let's use the relationship between momentum and momentum.
I = F t = Δp
in this case the final velocity is zero
F t = 0 -m v₀
F = m v₀ / t
in order to answer the question we must assume that the two vehicles have the same mass and speed
concrete barrier
F₁ = -p₀ / 0.1
F₁ = - 10 p₀
barrier collapses
F₂ = -p₀ / 1
let's look for the relationship of the forces
F₁ / F₂ = 10
therefore the first out is 10 times greater than the second barrier
When drinking at a private event, you should assume that drinks will be STRONGER THAN NORMAL.
At private events, some hosts have the habit of mixing different drinks together in order to increase the intoxicating power of the drinks. This does not normally happen when one is buying from restaurants or other commercial places. Thus, to be on the safe side, one should always assume that drinks will be stronger when one is attending a private event, this will caution one to drink responsibly in order to avoid intoxication.
Answer:
airplane
Explanation:
as greater mass greater inertia
The meter is the S.I.unit for length.
<h2>
Height of bridge is 83.66 m</h2>
Explanation:
We have equation of motion s = ut + 0.5 at²
Initial velocity, u = 25.3 m/s
Acceleration, a = 9.81 m/s²
Time, t = 2.29 s
Substituting
s = ut + 0.5 at²
s = 25.3 x 2.29 + 0.5 x 9.81 x 2.29²
s = 83.66 m
Height of bridge is 83.66 m
