The initial speed of the orange is zero in the downward direction and the height of the table is 4 ft then the correct option is B.
It is the study of the motion of a body without considering mass. And the reason behind them is neglected.
An orange rolls off a horizontal table with a speed of 0.5 ft./sec.
It hits the ground half a second later.
Then the height of the table will be
We know the formula
[tex]\rm s = ut + \dfrac{1}{2}at^2\\[/tex]
The final speed of the orange is zero because it hits the ground. Then we have
[tex]\rm -s = 0 \times 0.5+ \dfrac{1}{2}(-32)0.5^2\\\\-s = 0- 4\\\\s \ \ \ = 4[/tex]
The height of the table is 4 ft.
