Question

Мяч бросили вверх со 10м/с какую скорость он будет через о,5 секунд

Answer 1

Calculation of the Ball's Speed

To calculate the speed of the ball after 0.5 seconds, we can use the equation v = u + at, where: - v is the final velocity, - u is the initial velocity, - a is the acceleration, and - t is the time.

In this case, the ball is thrown upwards with an initial velocity of 10 m/s. Since the ball is thrown upwards, the acceleration due to gravity will act in the opposite direction, causing the ball to slow down. The acceleration due to gravity is approximately 9.8 m/s^2.

Using the equation v = u + at, we can calculate the final velocity of the ball after 0.5 seconds:

v = 10 m/s + (-9.8 m/s^2) * 0.5 s

Simplifying the equation, we get:

v = 10 m/s - 4.9 m/s^2

Therefore, the speed of the ball after 0.5 seconds will be 5.1 m/s.

Please note that this calculation assumes no air resistance and neglects any other external factors that may affect the motion of the ball.
