Two tug boats are towing a large boat, of mass 22500 kg, back to shore. tug boat 1 is pulling
with a force of 5500 n at an angle of 35◦ north of the forward motion (similar to worked
example 2) and tug boat 2 is pulling with a force of 4907.8 n at an angle 40◦
south of the
forward motion. if the large boat is being pulled with constant velocity, and there is a resistive
force to the motion, then what size is the resistive force?

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.

Avertical clean glass piezometer tube has an inside diameter of d = 1 mm and is used to measure pressure in a horizontal pipe carrying water as shown. due to pressure in the pipe, the water at 20c rises into the tube to a height h. if the water pressure in the pipe is p = 500 pa gauge, estimate the height h: (a) without considering surface tension (b) with surface tension (capillary) effects. the contact angle  can be assumed at 30 deg
