Two forces act on a 50 kg object. One force has magnitude of 65 N directed 55° clockwise from the positive x-axis, and the other has a magnitude of 40 N at 32° clockwise from the positive y-axis. What is the magnitude of this object’s acceleration?

An antelope is being pulled by two forces whose vector-component expressions are: F1 = 2Ni + -1.4Nj + -9.2Nk F2 = -2.4Ni + 1.7Nj + -9.6Nk What is the angle (in degrees) between these two vectors?

Two horizontal forces, and F2, are acting on a box, but only is shown in the drawing. F₂ can point either to the right or to the left. The box moves only along the x axis. There is no friction between the box and the surface. Suppose that F₁ = +4.6 N and the mass of the box is 3.6 kg. Find the magnitude and direction of F2 when the acceleration of the box is (a) +6.9 m/s², (b) -6.9 m/s², and (c) 0 m /s². (a) F₂ (b) F₁₂ (c) F₂ = II ◄► ◄► F₁ +x

If you have an object moving along a rough surface (one in which kinetic friction is a significant contributor) then kinetic energy will be conserved. True O False

Determine the force Q-> when the block moves with constant velocity. Express your answer in vector form.

A 3.0 kg block moves up on a rough 20° inclined plane with µk = 0.43. A force of 16 N parallel to the incline and up the incline is applied on the block. What is the acceleration of the block?

A 10 kg box experiences a force of 15 Newtons in the positive x-direction and 8 Newtons in the negative y-direction. What is the magnitude of the net force acting on the box? Answer in Newtons.

a 2 kg golf ball moves along an x axis according to x(t) = 10t^3 - 2.80t^2 + 7.4t +15 , with x in meters and t in seconds . in unit-vector notation , what is the net force acting on the particle at t= 5.20 s?

You and some friends are trying to help another friend pull his car out some mud by attaching three ropes tohis car. One friend insists that the three ropes should be attached in the fashion shown in the figure. Theforce applied by each rope is also shown in the figure. If the car has a mass of 1500 kg, what is the magnitudeand direction of the acceleration of the car?

A woman pushes a 10.0 kg box across a horizontal floor with a constant force of magnitude 40.0 N directed at an angle of -25° with respect to the positive x-axis. The box moves horizontally to the right. At the origin (x=0) the box has an initial speed of 4.00 m/s and the woman pushes it to a location ofx=3.00 m. what is the force of the woman? what is the force of gravity? what is the normal force of the floor?
