5) A mass m is connected to one end of a massless string of length L. The other end of the string is tied to a tall vertical pole of height H (much taller than L). The string is wound around the pole so that each wrap makes a small circle of the string and the mass touches the top of the pole. The mass is let go and the string begins to unwind. What is the angle o that...

please explain the answer
4) The escape velocity on the surface of a planet is given by 2GM R where G = 6.67 x 10-11m2 kg-1 3-2 is Newton's gravitational constant, M is the mass of the planet, and R is the radius of the planet. The escape velocity is the velocity you have to thrown an object so that it does not come back down (better hit the gym!). Write v in terms of average mass density p. Recall...

Conical Pendulum A mass attached at the end of a massless string swings around in a horizontal circle (the string sweeps out a cone). Let θ be the angle the string makes with the vertical, l be the length of the string, h is the vertical height of the string, and r is the radius of the circle. So, l is the hypotenuse of a right triangle with h and r as legs, and θ as the upper angle. The...

A mass is attached to one end of a massless string, the other
end of which is attached to a fixed support. The mass swings around
in a vertical circle as shown in Fig. 5.36. Assuming that the mass
has the minimum speed necessary at the top of the circle to keep
the string from going slack, at what location should you cut the
string so that the resulting projectile motion of the mass has its
maximum height located directly...

a small heavy bucket of mass m is tied to a massless rope of length l is swung around at the end of the rope in a vertical circle. what is the magnitude of the tension in the rope at the bottom of the buckets circular path when the bucket has a speed v?

A ball of mass 1.25 kg is attached by a 1.4 meter long massless
rope to the top of a vertical pole. The ball swings in a horizontal
circle at a constant rate of ? rad/s with the rope making
an angle of 29

A
swig sweat of mass M is connected to a fixed point P by a massless
cord of length L. A child also of mass M sits on the seats and
begins to swing with zero velocity at a position at which the cord
makes a 60 angle with the verticle shown in figure 1. The swing
continues down until the cord is exactly vertical at which time the
child jumps off in a horizontal direction. The swing continues in...

A mass m = 4 kg hangs on the end of a massless rope L = 1.91 m
long. The pendulum is held horizontal and released from rest.

In Figure below, a ball of mass m is connected by means of two massless strings to a rotating rod. The top string is length L. The strings are tied to the rod with separation d=L/2, and are taut. Rotating rod A) Draw and label all the forces on mass m. (6 pts.) B) Determine the angle between the upper and lower string at the ball. (3 pts.) C) What is the model for the radius of the circular path,...
A mass m = 5 kg is tied on one end of a rope and is...
A mass m = 5 kg is tied on one end of a rope and is forced to execute a circle on a vertical plane so that in completes one revolution every second. If the maximum tension that the rope can withstand is 1000 N, find the maximum length that the rope can have without breaking. Use g = 10 m/s2.
5) A mass m is connected to one end of a massless string of length L. The other end of the string is tied to a tall vertical pole of height H (much taller than L). The string is wound around the pole so that each wrap makes a small circle of the string and the mass touches the top of the pole. The mass is let go and the string begins to unwind.
