The two blocks are connected by a light string that passes over a frictionless pulley with a negligible mass. The 2 kg block lie
s on a rough horizontal surface with a constant coefficient of kinetic friction 0.4. This block is connected to a spring with spring constant 4 N/m. The second block has a mass of 8 kg. The system is released from rest when the spring is unstretched, and the 8 kg block falls a distance h before it reaches the lowest point. The acceleration of gravity is 9.8 m/s2 . Note: When the 8 kg block is at the lowest point, its velocity is zero. a. Calculate the falling distance h where the 8 kg blocks stops.
b. Consider the moment when the 8 kg block has descended by a distance of 21.168 m, where 21.168 m is less than h. At this moment calculate the sum of the kinetic energy for the two blocks. Answer in units of J.
Your pancreas makes a digestive juice that has enzymes that break down carbohydrates, fats, and proteins. The pancreas delivers the digestive juice to the small intestine through small tubes called ducts. Liver. Your liver makes a digestive juice called bile that helps digest fats and some vitamins.
