A block with mass of 10 kg is on a frictionless surface. One hand on the left side of the block is pushing it to the right. A second hand on the right side of the block is pushing it to the left.
The block starts from rest. Then Hand 1 pushes with a force of 8 N and the block moves to the right a distance of 4 m, where it has a final velocity of 2 m/s. Between its initial and final positions, how much work did Hand 2 do?

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...
A lighter block (3 kg) and a heavier block (12 kg) sit on a frictionless surface. Both blocks are initially at rest. The same force of 6 N then pushes to the right on each block for a distance of 16 m. What are the initial kinetic energies of the blocks? What are the changes in kinetic energy of the blocks? What are the final kinetic energies of the blocks? What are the initial momenta of the blocks? What are...

3. A block of mass m = 6.2 kg, moving on a frictionless surface with a velocity of -6.5 m/s to the right, collides with a block of mass M at rest, as shown in the figure. After the collision, the 6.2-Kg block recoils with a velocity of f =0.70 m/s to the left. If the blocks are in contact for 0.30 s, what is the magnitude of the average force on the 6.2-kg block, while the two blocks are...
