A lift accelerated downward with acceleration $'a'$. A man in the lift throws a ball upward with acceleration ${a_0}({a_0} < a).$ Then acceleration of ball observed by observer, which is on earth, is
A lift accelerated downward with acceleration $'a'$. A man in the lift throws a ball upward with acceleration ${a_0}({a_0} < a).$ Then acceleration of ball observed by observer, which is on earth, is
$(a + {a_0})$ upward
$(a - {a_0})$ upward
$(a + {a_0})$ downward
$(a - {a_0})$ downward
A lift accelerated downward with acceleration $'a'$. A man in the lift throws a ball upward with acceleration ${a_0}({a_0} < a).$ Then acceleration of ball observed by observer, which is on earth, is
The effective acceleration of ball observed by observer on earth = $(a -a_0)$
As ${a_0} < a,$ hence net acceleration is in downward direction.
