Question

a 100-lb body is attached to a rope and is pulled upward with a force of 150 lb. what is the acceleration of the body?

Answer 1

$m_1a_x=m_2g_x-m_1g_x ;a_x=\frac{m_2g_x-m_1g_x}{m_1};\\a_x=\frac{(m_2-m_1)\times g_x}{m_1}=\frac{(150-100)\times 9.8}{100}=4.9\frac{m}{s^2};\\ANSWER:the\ acceleration\ of \;the\;body\;is\\4.9\frac{m}{s^2}$
