Problem: A butterfly moves with a speed of v = 12.0 m/s. the y-components of its velocity is 8.00m/s.
Part A: Find the angle between the direction of its motion and the x-axis?
I need help to determine the angle between the direction of its motion and the x-axis.
For a submarine, identify when it will have the LEAST buoyant force acting on it. Suppose that neither the volume of the submarine nor the density of the water change.
A 3 meter long 200kg steel beam extends horizontally from the point where it has been bolted to the framework of a new building under construction.
A steel cable has a cross-sectional area 3.44 × 10-3 m2 and is kept under a tension of 1.53 × 104 N. The density of steel is 7860 kg/m3. Note that this value is not the linear density of the cable. At what speed does a transverse wave move along t..
