Racing greyhounds are capable of rounding corners at very high speeds. a typical greyhound track has turns that are 45m diameter semicircles. a greyhound can run around these turns at a constant speed of 12m/s .
what is its acceleration in m/s^2? what is its acceleration in units of g?

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.

The california mussel (mytilus californianus) attaches itself to a rock or other solid surface with a bundle of filaments known as the byssus. imagine that 15.0 j of work is done to stretch the distal end of the byssus. it releases 10.8 j of thermal energy as it relaxes. what is the resilience of the distal end of the byssus?

What are known as the properties of substances that describe a substance et does not change that substances?
