Question

Тело движется прямолинейно с ускорение 2 м/с. как изменится его скорость за 2 с?

Answer 1

A=Δv/Δt
Δv=a*Δt=2*2=4 м/с
=============================

Answer 2

4
Так как если 2 м\с, а у нас всего 2 секунды, то получится 2+2=4.
Вроде :)

Answer 3

Calculation of Change in Velocity

To calculate the change in velocity of an object moving in a straight line with an acceleration of 2 m/s² over a period of 2 seconds, we can use the formula:

Change in velocity = acceleration × time

Given that the acceleration is 2 m/s² and the time is 2 seconds, we can substitute these values into the formula:

Change in velocity = 2 m/s² × 2 s

Simplifying the equation, we find:

Change in velocity = 4 m/s

Therefore, the velocity of the object will change by 4 m/s over a period of 2 seconds.
