Question

Поезд движется прямолинейно со скоростью 15м/с какой путь пройдёт поезд за 10 с торможения происходящего с ускорением 0.5м/с2

Answer 1

S = 15*10 - 0,5*100/2 = 125 м

Answer 2

Calculation of Distance Traveled by the Train

To calculate the distance traveled by the train during the 10-second period of deceleration, we can use the equation:

distance = initial velocity * time + (1/2) * acceleration * time^2

Given: - Initial velocity (u) = 15 m/s - Time (t) = 10 s - Acceleration (a) = -0.5 m/s^2 (negative because it represents deceleration)

Plugging in these values into the equation, we can calculate the distance traveled by the train:

distance = 15 * 10 + (1/2) * (-0.5) * 10^2

Simplifying the equation:

distance = 150 - 0.5 * 0.5 * 100

distance = 150 - 0.25 * 100

distance = 150 - 25

distance = 125 meters

Therefore, the train will travel a distance of 125 meters during the 10-second period of deceleration.
