6. Solve parts a and b: A box is at rest on a horizontal, frictionless table.

a. Horizontal force F₁ points along the positive x-axis; when it is the only force acting on the box, the box accelerates at 8 m/s². Force F₂ is also horizontal; it has magnitude 5.31F₁ and acts at right angles to the direction of F₁.

If forces F₁ and F₂ act on the box at the same time, find the magnitude of the acceleration of the box now, in m/s².

6b. A box is at rest on a horizontal, frictionless table. Horizontal force F₁ points along the positive x-axis; when it is the only force acting on the box, the box accelerates at 7.39 m/s². Force F₃ is also horizontal; it has magnitude 7.2F₁ and acts at an angle 54.3^o to the direction of F₁.

If forces F₁ and F₃ act on the box at the same time, find the magnitude of the acceleration of the box now, in m/s².

A 1.1 kg mass is held at rest on top of a frictionless and horizontal table. A light string loops over a pulley which is in the shape of a 10 cm radius solid disk which has a mass of 1.1 kg. The light string then supports a mass of 1.1 kg which is hanging in air. The mass on the table is released and the suspended mass falls. What is the acceleration of the falling mass. What is the...
