To the end of a 50 cm long string, a ball of 100 g,
which is swinging under a vertical circle under the influence of
gravity, is tied. When the rope makes an angle = 12 ° with the
ball, the ball has a speed of 2.2 m / s. a) Find the current Radial
component of the acceleration (ar) b) When
angle = 18 °, find the magnitude of the tangential acceleration
(at). c) Find the magnitude of the total acceleration when angle =
18 °.

2. A 50 gram steel ball hangs from a 15 cm long string. The ball
is brought back to an angle of 15 degrees from vertical at the
bottom of the swing it contacts and bounces off the 25 gram ball on
a 15cm string. Find the angle of both balls.

The G string on a guitar is 69 cm long and has a fundamental
frequency of 196 Hz. A guitarist can play different notes by
pushing the string against various frets, which changes the
string's length. The third fret from the neck gives B♭ (233.08 Hz);
the fourth fret gives B (246.94 Hz).
How far apart are the third and fourth frets?
Express your answer to two significant figures and include the
appropriate units.

A 52 cm long thin string is attached to a 25 g mass. You bring
the mass up until you make a 4.2◦ angle with respect to the
equilibrium position and let go. You start the timer when the
simple pendula has a 2.1◦ angle with respect to the equilibrium
position. (a) What are the equations for the position, velocity,
and acceleration of the system? (b) Using your equations, determine
what the three will equal at the instant you let...

The G string on a violin is 30 cm long. when played without
fingering, it vibrates at frequency 196 Hz. The next higher notes
on the scale are A(220 Hz), B(247 Hz), C(262 Hz), and D(294 Hz).
How far from the end of the string must a finger be placed to play
these notes?

A 50 cm long rod is half aluminum and half copper. The aluminum
end is in boiling water. The end of an aluminum rod (50 cm long) is
maintained at 100 C by immersing in a pot of boiling water and the
other end at 00C by an ice-water mixture. If the cross-sectional
area of the rod is 1.3 cm2, how much will the rod melt in 20 min?
What will be the steady temperature at the Al-Cu junction?

A 100 g ball collides elastically with a 300 g ball that is at
rest. If the 100 g ball was traveling in the positive x-direction
at 5 m/s before the collision, what are the velocities of the two
balls after the collision?
