A block of mass M is pulled with a rope that exerts a force of a magnitude F, causing it to slide over horizontal ground with kinetic coefficient of friction p (use "mu" when you input your answer). The force is applied at angle theta (use "theta" when you input your answer) above the horizontal shown below. Resolve F into components using the coordinate system shown: F_x, F_y =, Find the sum of the force components in the y-direction acting...
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....
Consider the following three cases 1. The finger is pushing but not hard enough. Neither block moves 2. The finger is pushing hard enough that the two blocks are speeding up 3. The blodies have sped up, and are now moving at a constant speed. The finger still has to push to keep them going at a constant velodty. In all cases where the blocks are moving, they are moving together. (Block is not sliding on block A.) Block A...
. C. #1 : A block of mass M4 is positioned on top of another block of mass Mg that is moving towards the right. There is no friction bctween the lower block and the table but there is friction between the two blocks, with a coefficient of kinetic friction Au. The upper block is tied to the wall with a taut, ideal string that prevents it from moving along with MB. Another ideal string attached to the lower block...
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...
1)What is the uncertainty in the magnitude of the gravitational force on a block with mass m = 150±0.29 g? Consider acceleration due to gravity to be g=9.81 m/s2. Refer to the equations in the lab manual. 2)What is the magnitude of the gravitational force on a block with mass m = 234±1 g? Consider acceleration due to gravity to be g=9.81 m/s2 3)Consider the vector A, with magnitudes Ax = 128.3 N and Ay = 228.7 N. Calculate the...
Two blocks are connected by a light cord on a pulley. Block 1 has a mass of 2.0 kg and is being pulled along a rough surface. Block 2 hangs from the same cord and has a mass of 4.0 kg. Assume the cord does not stretch and the pulley is light and frictionless. The magnitude of the tension in the rope is 20 N. 1.) Draw a free body diagram of for each block 2.) What is the magnitude...
You are told that an object has zero acceleration. Two forces on the object are: F_1 has magnitude 2.4 N at 45 degrees above the +x-axis and F_2 has magnitude 4.8 N at 37 degrees below the -x-axis. What is the third force that must be acting on the object? THE ANSWER ALREADY PROVIDED IS CONFUSING, I THINK A) The vector F_3 has an x-component 5.5 N in the -x-direction and a y-component 4.6 N in the -y-direction. B) The...
Please help with this question.
1. The block shown in the figure has a mass of 612 Kg. The static coefficient of friction between the block and the supporting surface is 0.33 while the kinetic coefficient of friction is 0.26. Ignore the size of the block. Force Pis parallel to the incline while the 1000N force is vertical. a) If P = 2000 N, the shown block is (circle the correct answer) (5 points) a) in equilibrium b) moving up...
Block 1 (m1 = 7 kg) and block 2 (m2 = 9 kg) are adjacent to each other on the surface of a table. Block 2 is to the LEFT of block 1. A hand pushes horizontally on block 2 and causes both blocks to move to the right with an acceleration of magnitude 2 m/s2. The coefficient of kinetic friction between the block and the surface equals 0.4. On a sheet of paper, draw the free body diagrams for...
