Question

A=0.1 м/с² V=18 км/с = 5 км/с t-s-?​

Answer 1

Ответ:

1. 1м/МС=10м/с=36км/ч и 10км/миң=600км/ч

2. 0.1 м/с=0,36 км/ч и 0.5км/ч думаю дальше понятно

Answer 2

To find the time (t) it takes for an object to reach a velocity (V) from an initial acceleration (A), you can use the following kinematic equation:

V = A * t

Given: A = 0.1 m/s² V = 18 km/s (which should be converted to m/s) V = 5 km/s (which should also be converted to m/s)

First, let's convert the velocities from km/s to m/s: 1 km/s = 1000 m/s

So, V = 18 km/s * 1000 m/s/km = 18000 m/s V = 5 km/s * 1000 m/s/km = 5000 m/s

Now, you can solve for t using the equation:

5000 m/s = 0.1 m/s² * t

To isolate t, divide both sides by 0.1 m/s²:

t = 5000 m/s / 0.1 m/s² t = 50000 s

Now, let's convert the time from seconds to hours since the initial velocity is given in km/s:

1 hour = 3600 seconds

t = 50000 s / 3600 s/hour ≈ 13.89 hours

So, it would take approximately 13.89 hours for the object to reach a velocity of 5 km/s with an acceleration of 0.1 m/s².
