F=20 ньютонов В=3 метер а=0,5 метров t=2 сантиметров

To solve for the missing variable, we need to use the appropriate formulas.

F = ma

In this equation, F represents force, m represents mass, and a represents acceleration.

Given: F = 20 Newtons a = 0.5 meters

We can rearrange the equation to solve for mass: m = F / a

m = 20 Newtons / 0.5 meters

m = 40 kilograms

So, the mass is 40 kilograms.

Next, let's solve for time using the formula:

s = (1/2)at^2

In this equation, s represents distance or displacement, a represents acceleration, and t represents time.

Given: s = 2 centimeters (converted to meters, which is 0.02 meters) a = 0.5 meters

We can rearrange the equation to solve for time: t = √(2s / a)

t = √(2 * 0.02 meters / 0.5 meters)

t = √(0.04 / 0.5)

t = √0.08

t ≈ 0.2828 seconds

So, the time is approximately 0.2828 seconds.
