Unformatted text preview: Nicholas Charles Miller- PHY183, Spring 2010 - Physics for Scientists and Engineers I 1 Homework Set 4 Tension A box of mass 24.6 kg is lifted using a rope. If a, the acceleration of the box, is 5.7 m/s 2 (upward), what is T, the tension in the rope (in N)? You are correct. Your receipt is 156-6603 Acceleration Two masses, m 1 = 8 kg, and m 2 = 4 kg are connected with a rope running without friction over a pulley. What is the acceleration of mass m 2 in m/s 2 ? Use upward as positive. You are correct. Your receipt is 156-8836 Due date: Sun Feb 14 23:59:00 2010 Three objects with masses m 1 = 36.1 kg, m 2 = 19.8 kg, and m 3 = 12.5 kg are hanging from ropes that are redirected over pulleys. What is the acceleration of m 1 ? Negative numbers for downward, and positive numbers for upward, please. You are correct. Your receipt is 156-1628 An elevator cabin has a mass of 374.5 kg, and the combined mass of the people inside the cabin is 167.7 kg. The cabin is pulled upward by a cable, with a constant acceleration of 2.47 m/s 2 . What is the tension in the cable? You are correct. Your receipt is 156-9384 Nicholas Charles Miller- PHY183, Spring 2010 - Physics for Scientists and Engineers I 2 Homework Set 4 Two rectangular blocks are stacked on a table. The upper block has a mass of 8.9 kg, the lower block has a mass of 28.6 kg. The coefficient of kinetic friction between the lower block and the table is 0.11. The coefficient of static friction between the upper and the lower blocks is 0.199. A string is attached to the lower block, and an external force is applied in horizontal direction to pull on the string, as shown. What is the maximum force that one can apply without having the upper block slide off? You are correct. Your receipt is 156-5365 Consider the figure above, with M 1 =149 kg and M 2 =62.58 kg....
