Question

мальчик на самокате скатывается с горки с ускорением 0, 2 м/с2 какую скорость приобретает он через 10 секунд если его начальная скорость равна 1 м/с..

Answer 1

1 м/с + 0,2*10 = 3 м/с

Answer 2

Calculation of the Final Velocity

To calculate the final velocity of the boy on the scooter after 10 seconds, we can use the following formula:

Final velocity = Initial velocity + (Acceleration * Time)

Given that the initial velocity is 1 m/s and the acceleration is 0.2 m/s², we can substitute these values into the formula:

Final velocity = 1 m/s + (0.2 m/s² * 10 s)

Calculating the expression inside the parentheses:

Final velocity = 1 m/s + (2 m/s) = 3 m/s

Therefore, the boy on the scooter will acquire a velocity of 3 m/s after 10 seconds.

Please note that the above calculation assumes constant acceleration and neglects any other external factors that may affect the motion of the boy on the scooter.
