8 Figure P7 shows two crates with masses m1 = 5 kg and m2 = 10 kg, respectively, are connected by a rope through a massless pulley. As also shown in Figure P7, the crate of mass m1 is subjected to a force having a magnitude of F = 15 N and constant direction = 45. The system starts from rest with zero initial distance. The coefficient of kinetic friction between crate m1 and the ground is denoted as HK = 0.3. The magnitude of the gravitational acceleration is 9.81 m/s. Determine the speed of crate m and the distance it has travelled after 10 seconds. F TTT m Figure P7. A pulley system with two masses m and m m KEITH HEA
