Question

Велосипедист движется под уклон с ускорением 0.1м/с^2.Какая скорость будет через 30с , если его начальная скорость 5 м/с.

Answer 1

Calculation of the Final Velocity

To determine the final velocity of the cyclist after 30 seconds, we can use the equation of motion:

Final velocity = Initial velocity + (Acceleration * Time)

Given: - Initial velocity (u) = 5 m/s - Acceleration (a) = 0.1 m/s^2 - Time (t) = 30 s

Substituting the given values into the equation, we can calculate the final velocity:

Final velocity = 5 m/s + (0.1 m/s^2 * 30 s)

Calculating the expression within the parentheses:

Final velocity = 5 m/s + (3 m/s)

Adding the values:

Final velocity = 8 m/s

Therefore, the final velocity of the cyclist after 30 seconds will be 8 m/s.
