The figure below shows a block with mass m = 5.3 kg pulled up a ramp inclined at an angle of 6 = 28° with a force of magnitude F = 33 N parallel to the ramp. m (a) If there is no friction between the block and the ramp, what is the magnitude of the block's acceleration (in m/s2)? 1.485 Draw a free-body diagram. What forces act on the block? Let the x-axis be parallel to the incline. What...
Any help with this test prep question would be greatly appreciated. A block of mass M = 2.0 kg accelerates to the right on a surface with a kinetic coefficient of friction of MU_k = 0.30 pulled by a massless string which passes over a massless and frictionless pulley as shown. A block of mass m = 1.0 kg hangs freely from the other end of the string. Call the tension in the string T and the frictional force F_F....
004r no 2) A box sits on a table. In this example: a) Identify two forces that are an action-reaction pair (equal due to Newton's 3rd Law). b) Identify two forces that are an equilibrium pair (equal due to Newton's 1st Law). 3)A S kg box is on a ramp with a 10P incline (angle from the ground) The coefficient of statice friction is 0.3. The cofficient of kinetic friction is 0.2 a) Draw a free body diagram with all...
A hand pushes a 2 kg block along a table from point A to point C as shown in the figure below. The table has been prepared so that the left half of the table (from A to B) is frictionless. The right half (from B to C) has a non-zero coefficient of friction equal to . The hand pushes the block the full distance from A to C using a constant force of 5 N. The block starts off...

(a) As shown in Figure 4(a), a wooden block A with mass ma = 2.4 kg on a rough inclined plane is connected to a massless spring (k = 160 N/m) fixed to the top of the inclined plane. The angle of the inclined plane is @ = 37º and the coefficient of kinetic friction is uk = 0.30. The other end of block A is connected to block B via a massless cord passing over a pulley P of...
A hand pushes a 4 kg block along a table from point A to point C as shown in the figure below. The table has been prepared so that the left half of the table (from A to B) is frictionless. The right half (from B to C) has a non-zero coefficient of friction equal to u. The hand pushes the block the full distance from A to C using a constant force of 7 N. The block starts off...
1. A block with weight W = 30 N is on a flat horizontal surface. You pull to the right with a force F = 16 N. There is gravity present and the coefficient of friction is static = 0.4 and kinetic - 0.25. You are also pulling straight up with an applied force of 12 N. Now what are: The normal force N-_ the frictional force f- the net force on the block Foot and acceleration a = 2....
