Q. A block of mass 7 kg is placed on a smooth table. An unstretchable thread tied to it passes over a frictionless pulley and carries another mass of 3 kg at other end. The acceleration of the system isPhysics Question Image

Laws of Motion

Solution:

Here, Acceleration, $a = \frac{m_2}{(m_1 + m_2)} g = \frac{3 \times 10}{(7 + 3)} = 3 \, ms^{-2}$
