1. A horizontal curve with a radius of 800ft connects the tangents of a two-lane highway with a design superelevation of 0.06 and a coefficient of side friction of 0.14. Lanes are to be 12-feet wide and there is no median. Please calculate: a) What is the speed limit to be posted for a vehicle traversing this curve

Asher cycles 12 miles in 16 hours. what is his speed?

A1-lb collar is attached to a spring and slides without friction along a circular rod in a vertical plane. the spring has an undeformed length of 5 in. and a constant k =25 lb/ft. knowing that the collar is released from being held at a determine, the speed of the collar and the normal force between the collar and the rod as the collar passes through b.

Determine the net charge of the predominant form of arg at (a) ph 1.0, (b) ph 5.0, (c) ph 10.5, and (d) ph 13.5
