Acurve of radius 53.1 m is banked so that a car of mass 2.9 mg traveling with uniform speed 67 km/hr can round the curve without relying on friction to keep it from slipping on the surface.

The crank oa rotates in the vertical plane with a constant clockwise angular velocity ω0 of 5.6 rad/s. for the position where oa is horizontal, calculate the force under the light roller b of the 10.6-kg slender bar ab.

Why are graphs useful when interpreting data

If 2 different solids have the same masses but different volumes, how will their densities compare? a. the solids will have the same densities. b. the solid with lower volume will have a higher density. c. the solid with greater volume will have a higher density. d. the solid with greater volume will have double the density of the solid with the lower volume.
