Why do we say that a spring is elastic? Why do we say that a spring is elastic? It does not obey Hooke's law. When deformed, it returns to its original shape. It is made of rubber. When deformed, it does not return to its original shape.

Acompound machine is also called a machine. a. force b. simple c. complex d. directional

The rocket is fired vertically and tracked by the radar station shown. when θ reaches 66°, other corresponding measurements give the values r = 32700 ft, r¨ = 85 ft/sec2, and θ˙ = 0.019 rad/sec. calculate the magnitudes of the velocity and acceleration of the rocket at this position.

Apotter's wheel moves uniformly from rest to an angular speed of 0.20 rev/s in 32.0 s. (a) find its angular acceleration in radians per second per second. rad/s2 (b) would doubling the angular acceleration during the given period have doubled final angular speed?
