Academics

A toy cart is attached to a weight across a half-pulley as shown on the drawing. The cart is pushed away from the pulley with the velocity of v = 457.0 cm/s. The mass of the suspended weight is m_s=1.7 g, and the mass of the toy cart is m_cart=9.9 g, and friction is negligible.

How long will it take before the cart is moving with the same speed 457.0 cm/s, but back toward the pulley ?
