Question

футболист слегка ударил по мячу придав ему скорость 3м/с чему будет ровна скорость мяча через 6 с после удара если в резульиате трения о покрытие движется с ускорением в 0.25м/с^2?​

Answer 1

Скорость
v=v0+at
v=3+0,25×6=4,5 м/с
Ответ: 4,5м/с

Answer 2

Calculation of the ball's velocity after 6 seconds

To calculate the velocity of the ball after 6 seconds, we need to consider the initial velocity given and the acceleration due to friction.

Given information: - Initial velocity of the ball: 3 m/s - Acceleration due to friction: 0.25 m/s^2

Using the equation of motion, we can calculate the final velocity of the ball after 6 seconds:

Final velocity = Initial velocity + (Acceleration × Time)

Substituting the given values: Final velocity = 3 m/s + (0.25 m/s^2 × 6 s)

Calculating the final velocity: Final velocity = 3 m/s + 1.5 m/s Final velocity = 4.5 m/s

Therefore, the velocity of the ball after 6 seconds, considering the acceleration due to friction, is 4.5 m/s.
