In the figure, a cord runs around two massless, frictionless
pulleys. A canister with mass m = 42 kg hangs from one pulley, and
you exert a force F on the free end of the cord. (a) What must be
the magnitude of F if you are to lift the canister at a constant
speed? (b) To lift the canister by 4.0 cm, how far must you pull
the free end of the cord? During that lift, what is the...

To start her lawn mower, Julie pulls on a cord that is wrapped around a pulley. The pulley has a moment of inertia about its central axis of I = 0.520kg?m2 and a radius of 6.00cm . There is an equivalent frictional torque impeding her pull of ?f = 0.410m?N . A. To accelerate the pulley at ? = 4.70rad/s2 , how much torque does Julie need to apply to the pulley? B. How much tension must the rope exert?

You have two equal masses m1 and m2 and a
spring with a spring constant k. The mass m1 is
connected to the spring and placed on a frictionless horizontal
surface at the relaxed position of the spring. You then hang mass
m2, connected to mass m1 by a
massless cord, over a pulley at the edge of the horizontal surface.
When the entire system comes to rest in the equilibrium position,
the spring is stretched an amount d1 as shown...

question 2-4 please
1. Two boxes are connected by a light cord, which runs over a below. The coefficient of friction is 0.54. mi = 5 kg and m2 4 kg. a) Find the acceleration of the system. b) Find the tension in the cord (2 pts.) pulley. See fig. m2 2. The 3.5 kg mass on the incline frictionless plane shown below moves upwards under the action of a force of 18.08N parallel to the surface. The force acts...

A stone with mass m is suspended from the free end of a wire
that is wrapped around the
outer rim of a pulley, similar to what is shown in the figure. The
pulley is a uniform disk with mass
M and radius R and turns on frictionless bearings. You measure that
the stone travels a distance h
during a time interval of t starting from rest.
A) Find the mass of the stone in terms of m, M, h...

(III) A uniform rod AB of length 5.0 m and mass M = 3.8 kg is hinged at A and held in equilibrium by a light cord, as shown in Fig. 9-67. A load W = 22 N hangs from the rod at a distance d so that the tension in the cord is 85 N. (a) Draw a free-body diagram for the rod. (b) Determine the vertical and horizontal forces on the rod exerted by the hinge. (c) Determine...

A small mass M attached to a string slides in a circle (x) on a
frictionless horizontal table, with the force F
providing the necessary tension (see figure). The force is then
increased slowly and then maintained constant when M travels around
in circle (y). The radius of circle (x) is twice the radius of
circle (y).
Answer can be true,false,less than, greater than, equal to
