Question

Велосипедист двигаясь со скоростью 5м/с через 2 минуты разгоняется до 15 м/с определите с каким ускорением двигается велосипедист

Answer 1

15=5+x*2

2x=15-5

2x=10

х=10:2

х=5м/с^2

Answer 2

Calculation of Acceleration

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

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

Given: - Initial velocity (u) = 5 m/s - Final velocity (v) = 15 m/s - Time (t) = 2 minutes = 2 * 60 seconds = 120 seconds

Using the formula, we can calculate the acceleration:

a = (15 m/s - 5 m/s) / 120 s

Simplifying the equation:

a = 10 m/s / 120 s

Calculating the value:

a ≈ 0.0833 m/s²

Therefore, the cyclist is accelerating at approximately 0.0833 m/s².
