What is the acceleration and error of acceleration in a hanging system. There is a cart connected to a string on a pulley that accelerates due to a hanging mass. The mass of the cart and the string together is 511+-1g, gravity is 9.8+-0.03, the hanging mass is 55+-1g. Assuming there is no friction.

A child's swing is held up by two massless ropes tied to a tree branch. The distance between the ropes at the top of the swing is less than the distance between the ropes at the bottom, so that the ropes hang 14.01° from the vertical (see the picture). If the tension in each rope is 2.4 N, what is the weight of the swing?

The longer, top cord loops over a frictionless pulley and pulls with a force of magnitude 74 N on the wall to which it is attached. The tensions in the shorter cords are T1 = 40.0 N, T2 = 32.0 N, and T3 = 8.0 N.   What are the masses of each disk? (a) disk A kg(b) disk B kg(c) disk C kg(d) disk D kg

A block with a mass of 6.18kg slides down a ramp inclined at 30.0o.  The coefficient of kinetic friction between block and ramp is uk=0.490. The kinetic friction force acting on the block as it slides has a magnitude of ________N.

A heavy sled is being pulled by two people, as shown in the figure. The coefficient of static friction between the sled and the ground is µs = 0.603, and the kinetic friction coefficient is = 0.403. The combined mass of the sled and its load is m = 336 kg. The ropes are separated by an angle o = 25.0°, and they make an angle 0 = 31.1° with the horizontal. Assuming both ropes pull equally hard, what is the minimum rope tension required to get the sled moving? minimum rope tension: N If this rope tension is maintained after the sled starts moving, what is the sled's acceleration? acceleration: m/s2

A mass is suspended from the ceiling in an elevator by a heavy rope. The mass is 80 kg and the mass of the rope is 2 kg. If the breaking strength of the rope is 1000 N, what is the maximum acceleration of the elevator such that the rope will not break?

B h = 150 cm x = 50 cm L = 95 cm Mass = 0.8 kg at point G (so MMI = mL^2 about point A) At what acceleration (in m/s^2) will the object lift off the wall?

A steel beam is suspended from two ropes as it is lifted to the top of a building at a constant speed. One of the ropes makes an angle of 25.2 degrees with respect to the vertical and has a tension of 722 N, while the other makes an angle of 29.5 with respect to the vertical. What is the beam's mass in kg?

Two ideal pulleys (massless and frictionless) form a pulley system that can lift a weight by pulling on the end of a massless rope, as shown below. The upper pulley is attached to the ceiling at point A, and the lower pulley is connected to a box of mass M = 10.0kg. (a) What is the tension in the rope if the box is accelerating upwards with a = 2.00 m/s^2? (b) What is the tension force at point A at the ceiling?

What is the mass of the box?
