Abucket of mass 2.00 kg is whirled in a vertical circle of radius 1.20 m . at the lowest point of its motion the tension in the rope supporting the bucket is 27.0 n.
a) find the speed of the bucket (hint: draw a free-body diagram of the bucket at the bottom of the motion.
b) how fast must the bucket move at the top of the circle so that the rope does not go slack? (hint: draw a free-body diagram of the bucket at the top of the motion.)

Orque can be calculated by multiplying the force (n) applied at 90? to the lever arm at a distance (m) from the pivot point (point of rotation), the compound si unit for the torque is n? m. if the force (at 90? to the lever arm) applied is 15 n and it is applied at 2.0 m from the pivot point (point of rotation), what is the torque on the lever?

Agas is contained in a vertical, frictionless piston–cylinder device. the piston has a mass of 3.2 kg and a cross-sectional area of 35 cm2. a compressed spring above the piston exerts a force of 190 n on the piston. if the atmospheric pressure is 95 kpa, determine the pressure inside the cylinder.
