In the figure, a 1.68 kg ball is connected by means of two massless strings, each of length L = 1.86 m, to a vertical, rotating rod. The strings are tied to the rod with separation d = 1.86 m and are taut. The tension in the upper string is 52.0 N. What are (a) the tension in the lower string, (b) the magnitude of the net force on the ball, and (c) the speed of the ball?

A ball with a mass of 270 g is tied to a light string that has a
length of 2.40 m. The end of the string is tied to a hook, and the
ball hangs motionless below the hook. Keeping the string taut, you
move the ball back and up until it is a vertical distance of 1.16 m
above its equilibrium point. You then release the ball from rest,
and it oscillates back and forth, pendulum style. As usual,...

A horizontal wire is hung from the ceiling of a room by two
massless strings. The wire has a length of 0.22 m and a mass of
0.009 kg. A uniform magnetic field of magnitude 0.075 T is directed
from the ceiling to the floor. When a current of I = 31 A exists in
the wire, the wire swings upward and, at equilibrium, makes an
angle φ with respect to the vertical, as the drawing shows. Find

1. For a stationary ball of mass m = 0.200 kg hanging from a
massless string, draw arrows (click on the “Shapes” tab) showing
the forces acting on the ball (lengths can be arbitrary, but get
the relative lengths of each force roughly correct). For this case
of zero acceleration, use Newton’s 2nd law to find the
magnitude of the tension force in the string, in units of Newtons.
Since we will be considering motion in the horizontal xy plane,...

Two astronauts, each with a mass of 57 kg, are connected by a
6.4 m massless rope. Initially they are rotating around their
center of mass with an angular velocity of 1.9 rad/s. One of the
astronauts then pulls on the rope shortening the distance between
the two astronauts to 2.6 m. What is angular speed (in rad/s) of
the system at this new separation distance between the astronauts?
You may model each astronaut as a point particle.
