9. The baseball catcher throws a ball vertically upward and catches it in the same spot as it returns to themitt. At what point in the ball’s path does it experience zero velocity ?a. midway on the way upD. at the top of its trajectoryc. the instant it leaves the catcher’s handd. the instant before it an'ives in the catcher’s mitt

Respuesta :

Answer:

Explanation:

  • At what point in the ball’s path does it experience zero velocity ; This will occur at maximum height.
  • Because at maximum height, acceleration due to gravity comes into play with negligible air resistance.

Answer:

At the top of its trajectory

Explanation:

When the base ball catcher throws the ball vertically upwards, the ball is acting with a negative acceleration due to gravity (-g) . from the equations of motion where v =u +at,

As the body continues going up until it gets to its maximum height , the velocity tends towards zero.

The total displacement ,upwards and downwards is also equal to zero.
