The trustee made distributions of $8,400 to Linda and $16,000 to Lucy. The trust and both beneficiaries are cash basis, calendar year taxpayers. Calculate the trust's accounting income.
A 1000-kg car travelling at a speed of 32 m/s skids to a halt on wet concrete where f_k = 0.3. How long are the skid marks.
A worker pulls horizontally on a crate on a rough horizontal floor, causing it to move forward with constant velocity. In the figure, force is the pull of the worker and force is the force of friction due to the floor.
Two boats start together and race across a 46 km wide lake and back. Boat A goes across at 44 km/h and returns at 48 km/h. Boat B goes across at 27 km/h, and its crew, realizing how far behind it is getting, returns at 69 km/h. Turnaround times are n..

suppose that a projectile which is subject to a linear resistive force is thrown down with a speed of Vyo which is greater than the terminal speed Vterm. Describe and explain how the velocity varies with time, and make a plot of Vy against t for t..
A photon is scattered 60.0° during a collision with an electron, which is initially at rest and gains a speed of 6.00× 106 m/s during the collision
Two circuits contain an emf produced by a moving metal rod, like that shown. The speed of the rod is the same in each circuit, other than the bulb in circuit 1 has one-half the resistance of the bulb in circuit 2.
