In a cargo plane, the center of gravity must be between the front and rear landing gears in order to maintain a torque equilibrium. The front landing gears help counteract the torque provided by the rear landing gears in this case. A jet transport has a weight of 1.00 106 N an...

A lumberjack (mass = 98 kg) is standing at rest on one end of a floating log (mass = 220 kg) that is also at rest. The lumberjack runs to the other end of the log, attaining a velocity of +3.5 m/s relative to the shore, and then hops onto an identical floating log that is ini...

The space probe Deep Space I was launched on October 24, 1998. Its mass was 474 kg. The goal of the mission was to test a new kind of engine called an ion propulsion drive. This engine generated only a weak thrust, but it could do so over long periods of time with the consumpt...

A paraglider is flying horizontally at a constant speed. Assume that only two forces act on it in the vertical direction, its weight and a vertical lift force exerted on its wings by the air. The lift force has a magnitude of 1900 N. For both questions, take the upward directi...

it's one cable, with a crate tie at the bottom and a worker in the middle of the cable between the crate and whatever the top end is, and he is climbing upward with a=.620m/s^2
physics
A cable is lifting a construction worker and a crate The weights of the worker and crate are 915 and 1430 N, respectively. The acceleration of the cable is 0.620 m/s2, upward. what is the tension in the cable below the worker? what is it above the worker?
