(b) The famous Loma Prieta earthquake that stopped the 1989 World Series produced ground accelerations of up to 4.0 m/s² in the San Francisco Bay Area.

Consider a small object of mass m attached to one end of a string and whirled in a vertical circle of radiusR. In this case the acceleration of the object increases as it goes down the vertical circle and decreaseswhen it goes up the vertical circle. Hence the speed of the object changes continuously. Consider also that the speed of the object at the bottommost position is double its speed at the uppermost position. If s is the angle the string forms with the vertical direction, calculate: (a) The tension in the string in terms of the angles, the mass m of the object and fundamental constants. (b) The kinetic energy of the object in terms of theangle s, the mass m of the object and fundamental constants. The answer should be left as a formula rather than a value
A block of mass 40 kg is held at rest on a rough plane, inclined at an angle of 15 super ring operator to the horizontal, by a rope making an angle of 65 super ring operator to the plane. The magnitude of the tension in the rope is 345 N. Calculate the magnitude of the friction force, in newtons, to two significant figures.

A block of mass M is pulled along a horizontal, flat, and smooth (no friction) surface by a rope of mass m, on which a force ?⃗is acting. If we consider that the rope does not stretch out when it is pulled, then the block and rope will move under the same acceleration. Determine the value of such acceleration. Now, if the mass of the rope m is much smaller than the mass of the block M, then what is the approximate value of the acceleration?
