Answer:
Explanation:
Given
Two springs with spring constant and
(a)If they are stretched using the same force
Force
where and
are the extension in the spring
so
therefore
Work done is given by
thus
(b)If they are stretched the same distance
Thus
For same extension, work done by Force 1 is more
Since the lemon is falling without any air resistance, the only force acting on the lemon is the acceleration due to gravity.
But, since we know that the lemon is falling with a constant speed. There has to be another unknown force to balance the gravitational force. Which has been shown in the freebody diagram
