Question

Скорость шарика который скатывается по длинному наклонному желобу за 5 секунд возросла с 2 до 5 м/с. определите ускорение шарика

Answer 1

Дано V1=2 м/с  V2=5м/с t=5 с а- ?

a=/V2-V1)/t=3/5=0,6 м/с2

Answer 2

Calculation of the Acceleration of the Ball

To determine the acceleration of the ball, we can use the formula:

Acceleration (a) = Change in velocity (Δv) / Time taken (Δt)

Given that the velocity of the ball increased from 2 m/s to 5 m/s over a time period of 5 seconds, we can calculate the change in velocity:

Δv = Final velocity (V2) - Initial velocity (V1) = 5 m/s - 2 m/s = 3 m/s

Substituting the values into the formula, we get:

Acceleration (a) = Δv / Δt = 3 m/s / 5 s = 0.6 m/s²

Therefore, the acceleration of the ball is 0.6 m/s².
