In Fig. 5-54a, a constant horizontal force vec(F)_(a) is applied to block A, which pushes against block B with a 15.0 N force directed horizontally to the right. In Fig. 5-54b, the same force vec(F)_(a) is applied to block B, now block A pushes on block B with a 10.0 N force directed horizontally to the left. The blocks have a combined mass of 12.0 kg. What are the magnitudes of (a) their acceleration in Fig. 5-54a and (b) force vec(F)_(a) ?

The figure here shows two horizontal forces acting on a block on a frictionless floor. If a third horizontal force vec(F)_(3) also acts on the block, what are the magnitude and direction of vec(F)_(3) when the block is (a) stationary and (b) moving to the left with a constant speed of 5" m"//"s" ?

A 10 kg monkey climbs up a massless rope that runs over a frictionless tree limb and back down to a 15 kg package on the ground (Fig. 5-56). (a) What is the magnitude of the least acceleration the monkey must have if it is to lift the package off the ground? If, after the package has been lifted, the monkey stops its climb and holds on to the rope, what are the (b) magnitude and (c) direction of the monkey's acceleratiohn and (d) the tension in the rope ?

A particle of m=5kg is momentarily at rest at x= at t=. It is acted upon by two forces vec(F)_(1) and vec(F)_(2) . Vec(F)_(1)=70hat(j) N. The direction and manitude of vec(F)_(2) are unknown. The particle experiences a constant acceleration, vec(a) ,in the direction as shown in (figure) Neglect gravity. a.Find the missing force vec(F)_(2) . b. What is the velocity vector of the particle at t=10 s ? c. What third force, vec(F)_(3) is required to make the acceleration of the particle zero? Either give magnitude and direction of vec(F)_(3) or its components.
