A particle of mass M = 3kg is at rest at the origin on a horizontal frictionless plane until t = 0s. At that time, two forces, → F1 = (20, −20) N and → F2 = (16, 5) N, are applied to the particle. Determine the (a) velocity and (b) position of the particle at t = 4s.

  • (14.2) A block of mass m = 10 kg riding on a frictionless horizontal plane is...

    (14.2) A block of mass m = 10 kg riding on a frictionless horizontal plane is subjected to five forces. The weight of the block and the normal force of contact with the plane both act in the vertical direction, cancel, and may be henceforth ignored. Three applied forces, →F1 , →F2 , →F3 , act horizontally on the block. The information that we have been able to gather about the applied forces is summarised as follows: F1 = 10...

    5, (3 points) A mass m 300 g lies on a frictionless horizontal surface and is attached to a horizontal spring with a spring constant k = 3 N/m. A coordinate system is given such that the z axis is parallel to the motion of the mass under the action of the spring, and the origin is located at the un-stretched position of the spring. The position of the mass is given by: x(t) = A cos(wt + φ) At...

    The diagram below shows a block of mass m=2.00kg on a frictionless horizontal surface, as seen from above. Three forces of magnitudes F1=4.00N, F2=6.00N, and F3=8.00N are applied to the block, initially at rest on the surface, at angles shown on the diagram. (Figure 1) In this problem, you will determine the resultant (total) force vector from the combination of the three individual force vectors. All angles should be measured counterclockwise from the positive x axis (i.e., all angles are...
