Question

A cart of mass 0.5 kg is placed on a smooth surface and is connected by a string to a block of mass 0.2 kg. At the initial moment the cart moves to the left along a horizontal plane at a speed of 7 m/s $(U s e g = 9.8 m / s^{2})$

The acceleration of the cart is

\frac{2 g}{7}

towards right.
