A B Let's revisit a previous problem and add the force of friction. In the figure, block A has a mass of 2.67 kg. It rests on a smooth but not frictionless horizontal table and is connected by a very light horizontal string over an ideal pulley to block B, which has a mass of 3.28 kg. The coefficient of kinetic friction between block A and the table is 0.2. When block B is gently released from rest, how long does it take block B to travel 0.983 m? Note: Be careful! Be sure all quantities are expressed in standard units before calculating anything. Report your answer in seconds.

Cray-Zee is speeding along at 26 m/s as she approaches the level section of track near the loading dock of the Whizzer roller coaster ride. A braking system abruptly brings the 392-kg car (rider mas included) to a speed of 3 m/s over a distance of 5.7 meters Determine the magnitude (positive answer) of the braking force applied to Cray-Zee's car. Answer: N
As shown in figure, find that at what distance body A will attain a velocity of 3 m/s when starts from rest.Assume the coefficient of Friction as 0.2 and pulleys are frictionless and weightless.
Tendons are strong elastic fibers that attach muscles to bones. To a reasonable approximation, they obey Hooke's law. In laboratory tests on a particular tendon, it was found that, when a 0.255 kg object was hung from it, the tendon stretched 1.25 cm Part A Find the force constant of this tendon in N/m Express your answer in newtons per meter. Part B Because of its thickness, the maximum tension this tendon can support without rupturing is 145 N. By how much can the tendon stretch without rupturing, and how much energy is stored in it at that point? Express your answer in centimeters. Part C Express your answer in joules.
