Coplanar Forces acting on an object at different magnitudes and directions.

Three coplanar forces act on a 75000.0 kg object in outer space, where there is no gravity: 14.2 kN directed at 357°, 25.6 kN at 138°, and 16.4 kN at 255°.

What is the magnitude and direction of the acceleration?

If the object has an initial velocity of 17.5 miles/h directed at 58.6° in the same plane as all three forces, what will its velocity and position be after the force has been applied for 65.5 s?

What will the objects direction from the origin be and in what direction will it be moving assuming the force was applied at the origin of coordinates? All directions are with respect to the x direction.

This question considers the motion of an object of mass m sliding on the outside of a cylinder of radius R whose axis is horizontal. The motion occurs in the vertical plane, and the surface of the cylinder is rough — the coefficient of sliding friction is μ'. The diagram below shows the position of the object when it is at an

A ball of mass 2.9kg rests on a ramp that makes an angle of 28 degrees with the horizontal. It is held in place by a rope that makes an angle of 55 degrees with the horizontal. Assume that the only forcesacting on the ball are its weight, the tension in the rope and the normal reaction from the ramp. Take the magnitude of the a

Both ends of a rope of length 4.8m are attached to a horizontal beam, at points 4.2m apart. A chandelier hangs on the rope, 1.2m from one of its ends.

(a) Calculate the angles that the two sections of the rope make with the beam, in degrees correct to two decimal places. The chandelier has mass 1

On my last test, there is a question: an object with a mass of 5kg is acted upon by 4 separate forces that each have a magnitude of 10N. I understand that there could be different resulting accelerations of the object but i don't understand why or how which is why i got this answer wrong. In fact, i was totally lost. What are th

A particle is under the influence of a force F = -kx+(kx^3)/a^3 where k and a are constants and k is positive.
1) Find U(x) the potential energy
2) What happens when E (total energy) = (1/4)ka^3

The eight figures show various situations where blocks of different weights are attached by ropes to rigidly fixed objects or to other blocks, which are attached to fixed objects. The situations differ in a number of ways, as the figures show, but all situations represent static equilibrium (i.e. nothing is moving). The weights

2 forces parallel to the X axis do 14.7 Joules of work on a small tray while moving it 20.7 meters in the X direction across a gym floor. One of the forces has a value of +3.89 Newton's in the X direction. What is the other force?

Consider a force F acting on a particle that moves with a velocity v for F=(6N)i - (5N)j and v = (-5 m/s)i + (4 m/s)j
-What are the magnitudes of F and v?
