A crate of mass m = 12.80 kg is pulled by a massless rope up a 36.9° ramp. The rope passes over an ideal pulley and is attached to a hanging crate of mass m2 = 16.30 kg. The crates move %3D 1.29 m, starting from rest.

The figure shows two blocks connected by a cord (of negligible mass) that passes over a frictionless pulley (also of negligible mass). The arrangement is known as Atwood's machine. Block 1 has mass m1 = 1.4 kg; block 2 has mass m2 = 3.7 kg. What are (a) the magnitude of the blocks' acceleration and (b) the tension in the cord? (a) Number i Units (b) Number Units >

Two teams of nine members each engage in a tug of war. Each of the first team's members has an average mass of 72 kg and exerts an average force of 1350 N horizontally. Each of the second team's members has an average mass of 77 kg and exerts an average force of 1373 N horizontally.   (a) What is the acceleration (in m/s2 in the direction the heavy team is pulling) of the two teams?

The figure shows two blocks connected by a cord (of negligible mass) that passes over a frictionless pulley (also of negligible mass). The arrangement is known as Atwood's machine. Block 1 has mass m1 = 1.1 kg; block 2 has mass m2 = 2.1 kg. What are (a) the magnitude of the blocks' acceleration and (b) the tension in the cord? (a) Number i Units (b) Number i Units >

as a fish jump vertically out of the water, assume that only two significant forces act on it: an upward force F exerted by the tail fin and the downward force due to gravity. a force chinook salmon has a length of 1.50 m and a mass of 48.5 kg. if the fish is moving upward at 3.00 m/s as its head first breaks the surface and has an upward speed of 5.80 m/s after two-thirds of its length has left the surface, assume constant acceleration and determine the following. a. the salmon's  acceleration b. the magnitude of the force F during this interval

In (Figure 1), F={300i-100j+550k}NF= (300i-100j+550k)N. Determine the magnitude of the projection of the force FF acting along the cable BA◆◆. Express your answer to three significant figures and include the appropriate units. Figure 2m 6m 1 of 1 3m

Two blocks of mass m1 = 0.6 kg and m2 = 2.4 kg are connected by a massless string, as shown in the Figure. They are released from rest. The coefficent of kinetic friction between the upper block and the surface is 0.27. Calculate the speed of the blocks after they have moved a distance 53 cm. Assume that the pulley is massless and frictionless.

An antelope is being pulled by two forces whose vector-component expressions are: F1 = 3.6Ni + -8.9Nj + -3.7Nk F2 = 8.2Ni + -1.7Nj + 2.4Nk What is the angle (in degrees) between these two vectors?

The figure shows two blocks connected by a cord (of negligible mass) that passes over a frictionless pulley (also of negligible mass). The arrangement is known as Atwood's machine. Block 1 has mass m1 = 1.2 kg; block 2 has mass m2 = 1.7 kg. What are (a) the magnitude of the blocks’ acceleration and (b) the tension in the cord?

The steel I-beam in the drawing has a weight of 1.51 × 103 N and is being lifted at a constant velocity. What is the tension in each cable attached to its ends?
