A 66.0 kg person throws a 0.0410kg snowball forward with a ground speed of 25.0 m/s. A second person, with a mass of 57kg, catches the snowball.
A ship's mast reaches to a height of 15 meters above the surface of a 10-meter- deep lake. When the sun is 30 degrees above the horizon, how long will the shadow of the mast be on the bottom of the lake?
A person lifts a 5kg cement block a vertical distance of 2.3m and after that aeries the block horizontally a distance of 6m. Determine the work completed by the person and by the force of gravity in this process.
A uniform electric field of magnitude 256 V/m is directed in the negative y direction. A +12.9 uC charge moves from the origin to the point (x, y) = (20.0cm, 45.6 cm). What was the change in the potential energy of this charge? Through what potent..
