Question

a baseball is thrown straight up with a speed of 40 m/s what is its accelereation during this petiod​

Answer 1

Ответ:

Юаскетболбный мяч полетел вверх вправо с скоростью 40 метров в секунду

Answer 2

When a baseball is thrown straight up, its acceleration can be determined using the laws of motion. The acceleration of an object in free fall near the surface of the Earth is approximately equal to the acceleration due to gravity, which is about 9.8 m/s².

In this case, the initial velocity of the baseball is 40 m/s when it is thrown straight up. As the baseball moves upward, its velocity decreases due to the acceleration of gravity. At the highest point of its trajectory, the velocity becomes zero before it starts to fall back down.

Therefore, during the entire period of the baseball's upward journey, the acceleration remains constant at -9.8 m/s² (negative sign indicating acceleration opposite to the initial velocity direction).

So, the acceleration of the baseball during this period is approximately -9.8 m/s².
