Question

a ball is thrown vertically upwards in the air. if the air resistance is cannot be neglected, then the acceleration of the ball at the highest point is

Answer 1

At the highest point, velocity is zero.

Hence air resistance of the body will also be zero.

As the body is immersed in buoyant forces by air, it acts on the body for opposing gravity.

So acceleration of the body will be less than actual due to gravity.

Answer 2

Answer:

since air resistance is taken into account, the acceleration due to gravity as it goes up also decreases. Hence g will be less at the highest point.
