Question

At maximum height on trajectory which of projectile becomes zero A) Acceleration C Vertical velocity B) Velocity D) Horizontal velocity?why​

Answer 1

The vertical velocity component of a projectile is 0 at a maximum height due to action of acceleration due to gravity

which acts in the direction opposite to that of the velocity and reduces its values constantly.When the object reaches a maximum height its velocity becomes 0 and starts falling in downward direction along the direction of acceleration due to gravity.

Answer 2

Answer:

Vertical velocity becomes zero

Explanation:

when a projectile reaches maximum height (it cannot go higher) therefore at this point vertical velocity must be zero as vertical distance does not increase.

This occured due to upward acceleration being overcome by acceleration due to gravity. Therefore new vertical acceleration becomes acceleration due to gravity in downward direction. (thus it cannot be zero)

There is no effect on the horizontal velocity and therefore total velocity becomes equal to horizontal velocity at that point. (as vertical velocity is zero)
