Ball a of mass m is connected to one end of a massless stick
with length `, the other end of which is connected to a pivot.
the stick is held vertically above the pivot and is then given
an infinitesimal kick. it swings down, and at the bottom of its
motion it collides elastically with ball b, also of mass m, which
hangs from a string with length ` and which is initially at rest.
ball b picks up whatever speed ball a had and then swings
upward in circular motion.
(a) a what point does ball b leave its circular motion and enter
freefall projectile motion?
(b) how high does ball b go in the resulting projectile motion

Pl asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave

Question 1 (5 pts): what is the maximum distance for which you can you resolve the two individual headlights of an on-coming truck as two separate lights rather than one if the headlights are separated by 2.00 m and your eye has a diameter of 1.00 centimeter? assume a wavelength of 500 nm.

Ihave a density of 1.61g/cm^3 and a mass of 28g. find the missing value
