Question

Тралейбус начинает двигаться прямолинейно и равноускоренно с ускорением , модуль которого а=0.25м/с2 .определите модуль перемещения тралейбуса за промежуток времени t =8с

Answer 1

s=at^2/2

s=0.25*64/2=8метров

Answer 2

Calculation of Displacement for Trolleybus

To calculate the displacement of the trolleybus, we can use the equation for displacement under constant acceleration:

Displacement (s) = Initial velocity (u) * time (t) + 0.5 * acceleration (a) * time^2

Given: - Initial velocity (u) = 0 m/s (assuming the trolleybus starts from rest) - Acceleration (a) = 0.25 m/s^2 - Time (t) = 8 s

Calculation

Using the given values, we can calculate the displacement of the trolleybus:

s = 0 * 8 + 0.5 * 0.25 * 8^2

s = 0 + 0.5 * 0.25 * 64

s = 0 + 8

s = 8 meters

Therefore, the module of displacement of the trolleybus for the given time interval of 8 seconds is 8 meters.
