->> 100 m◆v=0 Answer: frictionless friction only here Answer: M Starting from rest, a small block of mass m = 0.25 kg slides down an incline from a height = 1 m. As it slides down, the block experiences a force of kinetic friction of constant magnitude fa= 1.8N only over a distance L= 0.2 m, as shown in the figure. The incline is frictionless everywhere else. After reaching the bottom of the incline, the block strikes a larger block of mass M=1.8 kg that is attached to a spring of spring constant k= 6.5 N/m. The large block was originally at rest. The blocks stick together upon impact and travel together on the frictionless horizontal surface. Assume that both blocks are subject to the regular force of gravity (g = 9.80665 m/s). (a) Determine the speed of the small block right before it collides with the larger block. m/s www m (b) Determine the speed of the combination of the two blocks immediately after the collision. Answer: m/s (c) Determine the compression of the spring when the combination of the two blocks comes to rest. 4
