Question

Скорость материальной точки за 10 с изменилась от 5 м/с до 8м/с. с каким ускорением двигалась материальная точка?

Answer 1

A=v/t=(v-v0)/t
a=(8-5)/10=3/10=0.3 m/s^2

Answer 2

Calculation of Acceleration

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

Acceleration (a) = (Final Velocity (v) - Initial Velocity (u)) / Time (t)

Given that the initial velocity (u) is 5 m/s, the final velocity (v) is 8 m/s, and the time (t) is 10 seconds, we can substitute these values into the formula:

Acceleration (a) = (8 m/s - 5 m/s) / 10 s

Simplifying the equation:

Acceleration (a) = 3 m/s² / 10 s

Therefore, the acceleration of the object is 0.3 m/s².
