Find the average braking force of a 1000 kg car moving at 10 m/s braking to a stop in 5 s.
Verdich [7]

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:

I = \Delta p\\F \Delta t = m \Delta v

where

F is the average breaking force

\Delta t = 5 s is the stopping time

m = 1000 kg is the mass of the car

\Delta v = -10 m/s is the change in velocity of the car

Solving the equation for F,

F=\frac{m \Delta v}{\Delta t}=\frac{(1000 kg)(-10 m/s)}{5 s}=-2000 N

If a ball leaves the ground with a vertical velocity of 5.46 m/s, how long does it take
kifflom [539]

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

How many ounces in a liter
Anarel [89]
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

Why does a shirt appear white outside on a sunny day?
Maru [420]
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.
