Point of release frictionless friction only here 160 As shown in the figure, a block of mass m 16.5 kg is released from rest (at position A) near the top of an incline that makes an angle of 32° with the horizontal. As it slides down, the block experiences kinetic friction (k = 0.5) only over a distance L = 1.6 m, as illustrated in the figure. The incline is frictionless everywhere else. After passing the section with friction, and sliding further down, the block encounters a spring (at position B) and compresses it an amount = 0.22 m (to point C), before ing momentarily to rest. The distance between points A and B is 5.5 m. The system is subject to the regular force of gravity (g = 9.80665 m/s²). (a) Determine the speed of the block at position B. UB= 0.75 m/s (b) Determine the force constant k of the spring. k = 1.5 N/m Instructions A 10:30 PM
