What would be the resultant for a displacement of 15 m to the east, followed by a displacement of 17 m in a direction 60o north of east and finally a displacement of 25 m in a direction 15o north of east? Please break this problem down into logical steps on how to solve this problem.
1. A spelunker (cave explorer) drops a stone from rest into a hole. The speed of sound is 343 m/s in air, and the sound of the stone striking the bottom is heard 1.57 s after the stone is dropped. How deep is the hole?
Consider the system with m1 = 24kg, m2 = 14.60kg, R = 0.1400m, and the mass of the pulley M = 5.0kg. Object m2 is resting on the floor, and object m1 is 4.600m above the floor when it is released from rest. The pulley axis is frictionless. The cor..
