Homework Answers
Note: The horizontal component of the applied force i. e. Fx is not taken into account as it is assumed that the static friction between the 10kg and 5kg block is enough to counter balance it, thereby making the system balanced(in terms of force) .

1a . A constant force of 32.3 N pulls on a 20 kg block on a horizontal surface. The force is directed at 30o above the horizontal. A friction force impedes the motion. If at the start of the motion the block was at rest and after 11 meters it has a velocity of 3, what is the coefficient of friction? 1b. What is the work done by the constant force when the block is moved 8 meters? 2.What constant,...

A 0.5 kg block of ice is sliding by you on a very slippery floor at 2.5 m/s. As it goes by, you give it a kick perpendicular to its path. Your foot is in contact with the ice block for 0.0035 seconds. The block eventually slides at an angle of 23 degrees from its original direction (labeled theta in the diagram). The overhead view shown in the diagram is approximately to scale. The arrow represents the average force your...

you give it a kick perpendicular to its path. Your foot is in
contact with the ice block for 0.0032 seconds. The block eventually
slides at an angle of 27 degrees from its original direction

Please help. Block 1 (m1 = 5kg) and block 2 (m2 = 6 kg) are
adjacent.
Block 1 (m1 5 kg) and block 2 (m2 6 kg) are adjacent to each other on the surface of a table. Block 2 is to the LEFT of block 1. A rope pulls on block 2 up and to the right with a vertical tension of 30 N upward, and both blocks move right with an acceleration of magnitude 3 m/s2. The coefficient...

Block B has a mass of 5 kg. It is pushed by a horizontal force F = 16+3 + 5 N to move from rest. At t=7s, Block B is about to strike Block A. Block A has a mass of 9 kg, and is at rest before the impact. During and after the impact, the force F disappears. After the impact, the two blocks couple and move together. Assuming no friction, determine the common velocity of the two coupled...
