Respuesta :

Answer:

Explanation:

( a ) At top position , vertical component of velocity will be zero .

So answer is position no (3)

b )

At position (3) which is the topmost position , acceleration is acting due to gravity , so it will be downwards.

c )

Horizontal component of acceleration at all points will be zero because gravity acts vertically downwards.

d )

Vertical displacement will be zero at position ( 1 ) and ( 5 )

e )

Displacement is maximum at extreme  position , ie at position ( 5 )

f )

Speed is highest at position (1) and it is lowest at position ( 3 )

From highest to lowest

( 1 ) , ( 2 ) , ( 3 )
