Ответ:
By using the third equation of motion,
By substituting the values,
→![0 = (V_A^2)+2ad](/tpl/images/0510/8970/883fd.png)
→![d = -\frac{V_A^2}{2a}](/tpl/images/0510/8970/97364.png)
and,
→![d_2 = -\frac{(V_B)^2}{2a} = -\frac{4 V_A ^2}{2a}](/tpl/images/0510/8970/1939a.png)
hence,
→![d_B = 4d_A](/tpl/images/0510/8970/b2507.png)
Thus the above response is appropriate.
