An 8 kg block is positioned on a rough, inclined surface and attached to a wall via a rope as shown in the figure below.The tension in the rope is 3.2 N. The rope is cut. When the rope is cut, what is the initial acceleration of block down the slope? (Assume µs = 0.63 and θ = 30◦ .)

The correct answer is 0 m/s^2 but can you explain how to get there

A spring is attached to a wall, and a 0.50 kg block is attached to the other end of the spring. The spring-block system sits on a frictionless surface so that the block is able to oscillate without losing energy. The spring constant of the spring is k = 25 N/m. The block is pushed so that it compresses the spring by 20 cm beyond its equilibrium position. The block is released from rest at exactly the same time as...
