Question

Cord p 60° String A pendulum consists of a small object of mass m fastened to the end of an inextensible cord of length L. InA.) Determine the tension in the cord before the string is burned

B.) Show that the cord, strong enough to support the object before the string is burned, is also strong enough to support the object as it passes through the bottom of the swing

C.) The motion of the pendulum after the string is burned is periodic. Is it also simple harmonic? why or why not?

    Please show work Two particles of m_1 and m_2 are connected by a light, inextensible string of total of mass length L, which passes through a smooth hole in a smooth horizontal table. The mass m_2 is suspended below the table, and the mass m_1 moves in a circular motion on the table with an initial distance R_0 from the hole. A gravitational field g acts on this system. The mass m_1 starts out with speed v_0 on the table...

    2) In the above diagram of a pendulum, a mass, m, hangs on a massless cord of length, L, from the ceiling. Suppose the mass is pulled to the side so that the string makes an angle θ with the vertical. It is then released from rest at time t-0 and so it swings back and forth with no friction of any kind. You must use the energy method as used in the first problem (mass on a spring) in...

    Refer to diagram 4. Before solving, please convert 18.4 g to kg!!! and please put the final answer to 3 significant figures thank you so much! A pendulum consists of point mass 18.4 g on the end of a 0.425 m massless string. The mass is pulled aside so the string makes an angle θ = 36o with the vertical (as shown) and released with initial speed vo = 3.82 m/s downward (but perpendicular to the string). Assume there is...
