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
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.
