Answer:
Step-by-step 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 )
