Answer:
-2000 N
Explanation:
To solve the problem, we can use the impulse theorem, which states that the impulse is equal to the change in momentum of the car:

where
F is the average breaking force
is the stopping time
m = 1000 kg is the mass of the car
is the change in velocity of the car
Solving the equation for F,

Answer:
0.557 s
Explanation:
Given:
v₀ = 5.46 m/s
v = 0 m/s
a = -9.8 m/s²
Find: t
v = at + v₀
0 m/s = (-9.8 m/s²) t + 5.46 m/s
t = 0.557 s
One liter is equivalent to around 34 ounces (33.81 more exactly).
Fun fact: there are different ounces. So if you meant the imperial ounce then one liter would be equivalent to 35.2 ounces
The shirt absorbs the sunlight, so it appears white. All the light is reflected, so the shirt appears white. The sunlight refracts when it hits the shirt, so the shirt appears white.
