## Physics

A 1.07 kg block slides across a horizontal surface directly toward a massless spring with spring constant 4,794 N/m. The surface is frictionless except for a rough patch of length 0.461 m that has coefficient of kinetic friction 0.358. The initial velocity

## physics

Two blocks, A and B (with mass 50 kg and 100 kg, respectively), are connected by a string, as shown in Figure P5.64. The pulley is frictionless and of negligible mass. The coefficient of kinetic friction between block A and the incline is µk = 0.25.
