A 3.6 kg box is held at rest by two ropes that form 30 angles with the vertical. An external force F acts vertically downward on the box. The force exerted by each of the two ropes is denoted by T.
 
  A force diagram, showing the four forces that act on the box in equilibrium, is shown in Figure 5.6. The force F is adjusted so that the magnitude of force T is equal to the weight w. The magnitude of force F, for which this occurs, is closest to: A) 26 N
  B) 27 N
  C) 28 N
  D) 29 N
  E) 30 N

Question 2

A block lies on a horizontal frictionless surface. A horizontal force of 100 N is applied to the block giving rise to an acceleration of 3.0 m/s2.
 
  (a) Determine the mass of the block.
  (b) Calculate the distance the block will travel if the force is applied for 10 s.
  (c) Calculate the speed of the block after the force has been applied for 10 s.
