In the figure here, a stationary block explodes into two pieces L and R that slide across a frictionless floor and then into regions with friction, where they stop. Piece L, with a mass of 2.8 kg, encounters a coefficient of kinetic friction µL = 0.35 and slides to a stop in distance di = 0.45 m. Piece R encounters a coefficient of kinetic friction µR = 0.48 and slides to a stop in distance dr = 0.45 m. What was the mass of the block? rH = 0 HR dr Number Unit

In the figure here, a stationary block explodes into two pieces L and R that slide across a frictionless floor and then into regions with
friction, where they stop. Piece L, with a mass of 2.8 kg, encounters a coefficient of kinetic friction µL = 0.35 and slides to a stop in
distance di = 0.45 m. Piece R encounters a coefficient of kinetic friction HR = 0.48 and slides to a stop in distance dr = 0.45 m. What was

In the figure, block 2 (mass 1.80 kg) is at rest on a frictionless surface and touching the end of an unstretched spring of spring constant
180 N/m. The other end of the spring is fixed to a wall. Block 1 (mass 1.60 kg), traveling at speed v1 = 4.70 m/s, collides with block 2, and
the two blocks stick together. When the blocks momentarily stop, by what distance is the spring compressed?
