Question

Each propeller of the twin-screw ship develops a full-speed thrust of F = 375 kN. In maneuvering the ship, one propeller is turning full
speed ahead and the other full speed in reverse. What thrust P must each tug exert on the ship to counteract the effect of the ship's
propellers?

A 1500-N crate is to be held in place on a ramp that rises at 30.0° above the horizontal (see figure). The massless rope attached to the crate makes a 22.0° angle above the surface of the ramp. The coefficients of friction between the crate and the surface of the ramp are uk = 0.450 and us = 0.650. The pulley has no appreciable mass or friction. What is the MAXIMUM weight w that can be used to hold this crate stationary on the ramp? %3D W= ? Crate 22.0° Ramp 30.00
A jet airplane is in level flight. The mass of the airplane is m 8970 kg. The airplane travels at a constant speed around a 9.77 mi and makes one revolution every T 0.129 h. Given that the lift force acts circular path of radius R perpendicularly upward from the plane defined by the wings, what is the magnitude of the lift force acting on the airplane? R L kN At what angle is the airplane banked? x10

While two forces act on it, a particle is to move at the constant velocity = (3.58 m/s) -(-3.26 m/s). One of the forces is F1 = (1.88 N) + (-5.85 N). What is the other force? Number i + i j Units
A cord passing over a pulley connects two masses, as shown, where m, = 3.60 kg and m, = 7.10 kg. The system accelerates with a magnitude of 1.34 m/s?. The coefficient of kinetic friction between the masses and the incline is the same for both masses. Assume the pulley is frictionless, and the cord is massless. (Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.) m2 m, 35.0° 35.0° (a) What is the coefficient of kinetic friction? (b) What is the tension (in N) in the cord?
A 17 kg block rests on a 32 degree inclined frictionless surface and is attached by a light string to a 34 kg hanging mass where the string passes over a massless frictionless pulley. If g = 9.8 m/s^2 what is the tension in the connecting string?
