Question

V=18м/с S=450 t=30 v0-?

Answer 1

Відповідь:

12 м/c

Пояснення:

s=v0t+at^2/2

a=(v-v0)/t

2s=v0t+vt

v0=(2s-vt)/t=12 м/c

Answer 2

It looks like you're dealing with a physics problem involving velocity, initial velocity, displacement, and time. The given information is as follows:

• Final velocity (v): 18 m/s
• Displacement (S): 450 meters
• Time (t): 30 seconds
• Initial velocity (v0): Unknown

You can use the kinematic equation to solve for the initial velocity (v0):

$S = v_0 \cdot t + \frac{1}{2} a \cdot t^2$

However, in this case, since there is no information given about acceleration (a), we can use a simplified equation since acceleration could be assumed to be zero (as is the case for many basic physics problems):

$S = v_0 \cdot t$

Now plug in the values:

$450 = v_0 \cdot 30$

Solve for $v_0$:

$v_0 = \frac{450}{30} = 15 \, \text{m/s}$

So, the initial velocity ($v_0$) is 15 m/s.
