A spring (k= 12 N/m), which can be stretched or compressed, lies flat on a frictionless table. One end of the spring is attached to the wall, and the other has a 3.3 kg mass attached. Assume the equilibrium position is labelled zero. A student pulls the mass out to x=14.0cm and releases it from rest at time t=0. The mass oscillates as a SHM. What is the speed of the mass at time t=14.4 s? Answer: Check

A sphere of radius R can rotate about a vertical axis on frictionless bearings (see figure below). Let the rotational inertia of the sphere be A massless cord passes around the equator of the sphere, over a pulley with rotational inertial and radius r, and is attached to a small object of mass m. There is no friction on the pulley's axle and the cord does not slip on the pulley. At 1 = 0, the mass m has speed...

A sphere of radius R can rotate about a vertical axis on frictionless bearings (see figure below). Let the rotational inertia of the sphere be Isphere. A massless cord passes around the equator of the sphere, over a pulley with rotational inertia I pulley and radius r, and is attached to a small object of mass m.

The figures to the right show a rod with length, \(l\), and mass, \(M\), on a frictionless table rotated an angle \(\theta\) from the horizontal. It is fix to the table by a pin through its center of mass, and can rotate freely about this pin. On the two ends of the rod are connected identical springs with spring constant, \(k\), and the equilibrium position of the springs is when \(\theta=0\). In this problem, \(\theta \ll 1 \mathrm{rad}\), and the...

A block with mass m = 14 kg rests on a frictionless table and is accelerated by a spring with spring constant k = 4174 N/m after being compressed a distance x1 = 0.512 m from the spring’s unstretched length. The floor is frictionless except for a rough patch a distance d = 2.7 m long. For this rough path, the coefficient of friction is μk = 0.44. 1) How much work is done by the spring as it accelerates...

Problem 12: (10 points) PS 7-71: A spring with spring constant k is stretched a distance x and hooked onto a block of wood of mass m, which sits on a lab table. Then you release the block. The kinetic friction force between the block and the lab table is F equilibrium length? (VS) length? (Vs) initial stretch of x 65 cm, and a constant friction force Fi 2.4 N. (a) What is the initial elastic potential energy stored in...

A block slides from rest, along a track with an elevated left
end, a flat central part, into a relaxed spring, as shown in the
figure. The curved portion of the track is frictionless, as well as
the first portion of the flat part of L = 10 cm. The coefficient of
kinetic friction between the block and the only rough part, D = 10
cm, is given by k = 0.20. Let the initial height of the block be...

A block with mass m = 16 kg rests on a frictionless table and is accelerated by a spring with spring constant k = 4850 N/m after being compressed a distance x1 = 0.51 m from the spring’s unstretched length. The floor is frictionless except for a rough patch a distance d = 2.5 m long. For this rough path, the coefficient of friction is μk = 0.45. How much work is done by the spring as it accelerates the...
