Two horizontal forces act on a 2.0 kg chopping block that can slide over a friction less kitchen counter, which lies in an xy plane. One force is F_1 = (3.0 N)i + (4.0 N)j. Find the acceleration of the chopping block in unit-vector notation when the other force is (a) F_2 = (-3.0 N)i + (-4.0 N)j. (b) F_2 = (-3.0 N)i + (4.0 N)j, and (c) F_2 = (3.0 N)i + (-4.0 N)j.
A horizontal force of 40 N acting on a block on a frictionless level surface produces an acceleration of 2.5 m/s2. A second block, with a mass of 4.0 kg, is dropped onto the first. What is the magnitude of the acceleration of the combination of blocks if the same force continues to act? (Assume that the second block does not slide on the first block.)
A 3.9 kg block is being pushed across a frictionless horizontal surface by a horizontal force. The block accelerates at 5.6 m/s2. What is the magnitude of the normal force the surface exerts on the block? Express your answer in newtons and round to one decimal place.
(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...

Two forces act on a 3.20 kg object, the gravitational force and a second, constant force. The object starts from rest and in 1.20 s is displaced (4.251 - 3.301) m. Write the second force in unit vector notation. (Enter your answer in kg. m/s. Assume the gravitational force acts in the - direction.) = (18.888)i + (17.152); First, find the acceleration vector using kinematics, then substitute into Newton's second law to determine the unknown force vector. Recall that the...
The figure shows an overhead view of a 0.02 kg lemon half and two of the three horizontal forces that act on it as it is on a frictionless table. Force 1 has a magnitude of 8 N and is at 62 = 31°.

Problem 5: A block with a mass of m=37 kg rests on a frictionless surface and is subject to two forces acting on it. The first force is directed in the negative x-direction with a magnitude of F1=8.5 N. The second has a magnitude of F2 = 19.25 N and acts on the body at an angle θ = 17° measured from horizontal, as shown.Part (a) Please use the interactive area below to draw the Free Body Diagram for this...
