A one-meter long stick ("meter stick") has mass 120 grams, and is hinged at one end (pivot). Assume that the center-of-mass is 50 cm from either end. Calculate the rotational inertia of the stick. Answer in kg·m2.
The front end of an automobile has been designed so that upon impact it progressively crumples by as much as .70m. What is the magnitude of the deceleration
Ultrasound intensity level: Beta = 10Log (I2/I1), I1 and I2 = intensity at different locations/times An ultra sound signal is sent under sea water (v=1530m/s) to detect the location of an object. Determine the location of the object from the source
