please explain the answer
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...

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...

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?

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 rock of mass 13 kg is tied to a string of length 2.5 m, with the other end of the string fastened to the ceiling of a tall room. While hanging vertically, the rock is given an initial horizontal velocity of 2.1 m/s. How high will the rock swing? Express your answer in terms of the angle θ that the string makes with the vertical when the rock is at its highest point.
A rock of mass m = 0.97 kg is attached to a massless string of length...
A rock of mass m = 0.97 kg is attached to a massless string of length L = 0.71 m. The rock is swung in a vertical circle faster and faster up to a speed of v = 2.4 m/s, at which time the string breaks. What is the magnitude of the tension, in newtons, at which the string breaks?

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.
1)
How fast is the mass moving at the bottom of its path?
m/s
2)
What is the magnitude of the tension in the string at the bottom
of the path?
N
3)
If the maximum tension the string can take without breaking is
Tmax = 337 N, what is the maximum...

A massless rigid rod whose length L = 21.0 cm has a ball of mass
m = 0.079 kg attached to one end (see Figure). The other end is
pivoted in such a way that the ball will move in a vertical circle.
The system is launched from the horizontal position A with an
initial downward speed v0. The ball just reaches point D
and then stops. Calculate v0.
