Determine the acceleration (in m/s2) of a pterodactyl that changes velocity from 15.5 m/s [N] to 65 km/h [N] in 4.8 s

Protons and neutrons are found within the nucleus of an atom

The coefficient of friction is a number that represents the resistance to sliding between two in contact with one another.

Use the profile illustrated for problem (1). assume that the layer of silty sand fill (sm) is placed over the entire site. estimate the thickness of the fill (h - in feet) that will cause the effective vertical stress at the center of the clay layer to increase by 517.5 pounds per square foot.
