Question

A ball which is thrown vertically upwards reaches a certain height and falls down.
(a)What will be the velocity of an object when it reaches the maximum highest point?
(b)Name the force responsible for its downward displacement.

Answer 1

Answer:

Given :

A ball which is thrown vertically upwards

reaches a certain height and falls down.

To find :

(a)What will be the velocity of an object

when it reaches the maximum highest point?

(b)Name the force responsible for its

downward displacement.

Solution :

a ) The velocity of an object when it reaches the maximum highest point is 0 m / s² because that is the time phase when it starts to fall down .

b ) Gravity is the force responsible for its downward displacement.
