Classical Mechanics (Force)¶ You should know¶ Newton's Second Law $$ F = ma $$ Solution¶ The force $F_A$ is $$F_A = m_A \ a_A.$$ Since $m_B = 2m_A$ and $a_B = 2a_A$, thus $$ F_B = m_B \ a_B = (2m_A)(2a_A) = 4F_A. $$ Answer¶ (E) $F_B = 4F_A$ Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window)Click to share on Reddit (Opens in new window)Click to email this to a friend (Opens in new window)Click to print (Opens in new window)
