Two objects are connected by a very light flexible string as shown in the figure, where M = 0.60 kg and m = 0.40 kg. You can ignore friction and the mass of the pulley.
 
  (a) Draw free-body diagrams for each object.
  (b) Calculate the magnitude of the acceleration of each object.
  (c) Calculate the tension in the string.
  What will be an ideal response?

Question 2

A wooden block A of mass 4.0 kg slides on a frictionless table when pulled using a massless string and pulley array by a hanging box B of mass 5.0 kg, as shown in the figure.
 
  What is the acceleration of block A as it slides on the frictionless table? Hint: Think carefully about the acceleration constraint.
 
  A) 4.1 m/s2
  B) 3.5 m/s2
  C) 3.1 m/s2
  D) 2.7 m/s2

The use of salicylates dates back 2,500 years to Hippocrates's recommendation of willow bark (from which a salicylate is derived) as an aid to the pains of childbirth. However, overdosage of salicylates can harm body fluids, electrolytes, the CNS, the GI tract, the ears, the lungs, the blood, the liver, and the kidneys and cause coma or death.

Did you know?

For about 100 years, scientists thought that peptic ulcers were caused by stress, spicy food, and alcohol. Later, researchers added stomach acid to the list of causes and began treating ulcers with antacids. Now it is known that peptic ulcers are predominantly caused by Helicobacter pylori, a spiral-shaped bacterium that normally exist in the stomach.
