18 A flexible rope of mass m and length L slides without friction over the edge of a table. Let x be the length of the rope that is hanging over the edge at a given moment in time (a) Show that r satisfies the equation of motion/dt2 -gr/L. Hint: Use F-dp/ dt, which allows you to handle the two parts of the rope separately even though mass is moving out of one part and into the other (b) Give...

A uniform flexible chain of length L, with mass per unit length A, passes over a small (radius is negligible), frictionless pulley, as shown in figure 1. One side of the chain with length x is tied to a block with mass m. The chain and block are released
A uniform flexible chain of length L, with mass per unit length
A, passes over a small (radius is negligible), frictionless pulley,
as shown in figure 1. One side of the chain with length x is tied to
a block with mass m. The chain and block are released from a
rest position at t = 0 s. (Hint: the chain can be treated as a rope
with non-negligible mass)a. Find x such that the chain and the block are...

Blocks A and B areconnected by a massless stringof fixed length. The string slides over a pulley without any friction. Block A has a mass of 2??and block B has a mass of 1??, as shown. The blocks have just this instant been released from rest. a.Will the speed of block A be greater than, equal to, or less than the speed of block B? Will the blocks accelerate? If yes, will the blocks have the same magnitude of acceleration,...

3. As shown in the figure below, a block weighing 14.0 N, which slides without friction on a 45.0° incline, is connected to the top of the incline by a massless spring of unstretched length 0.450 m and spring constant 120 N/m. (a) How far from the top of incline does the block stop i.e. reach equilibrium ? (b) If the block is pulled slightly down the incline and released, what is the time to reach the new equilibrium position...

A 4.00-m length of light nylon cord is wound around a uniform cylindrical spool of radius 0.500 m and mass 1.00 kg. The spool is mounted on a frictionless axle and is initially at rest. The cord is pulled from the spool with a constant acceleration of magnitude 2.74 m/s2. (a) How much work has been done on the spool when it reaches an angular speed of 6.55 rad/s? _______J (b) How long does it take the spool to reach...
