Question

Вагонетка начала движение с ускорением 25 см/с^2. Найдите скорость движения вагонетки за 10 с.

Answer 1

A=0.25 м/с2    t=10 c     vo=0     v=?
===
v=vo+a*t=0+0.25*10=2.5 м/с
=========================

Answer 2

Calculation of the Velocity of the Wagonette

To find the velocity of the wagonette after 10 seconds, we can use the equation of motion:

v = u + at

where: - v is the final velocity - u is the initial velocity (assumed to be 0 since the wagonette starts from rest) - a is the acceleration - t is the time

Given that the wagonette starts with an acceleration of 25 cm/s^2 and the time is 10 seconds, we can substitute these values into the equation to find the velocity:

v = 0 + (25 cm/s^2) * (10 s)

Calculating this expression gives us:

v = 250 cm/s

Therefore, the velocity of the wagonette after 10 seconds is 250 cm/s.
