Question

байдарка с гребцом прошла расстояние 1000м от старта до финиша со скорость 5м/с.После прохождения линии финиша гребец начал тормозить.Ускорение байдарки постоянно и по модулю равно 0.5 м/с^2. На каком расстоянии от линии старта окажется байдарка через 10с после прохождения финишной черты?

Calculation of the Distance Traveled by the Kayak

To calculate the distance traveled by the kayak after crossing the finish line, we need to consider the initial velocity, the acceleration, and the time elapsed.

Given: - Initial velocity (v0) = 5 m/s - Acceleration (a) = -0.5 m/s^2 (negative because it represents deceleration) - Time elapsed (t) = 10 s

To find the distance traveled, we can use the following kinematic equation:

d = v0 * t + (1/2) * a * t^2

Substituting the given values:

d = (5 m/s) * (10 s) + (1/2) * (-0.5 m/s^2) * (10 s)^2

Simplifying the equation:

d = 50 m - 25 m = 25 m

Therefore, the kayak will be located 25 meters from the starting line after 10 seconds of crossing the finish line.
