Radio waves (419m) from a station travel along two paths from the transmitter to a house. The first path is direct, 27km, and the second path is by reflection from a mountain directly behind the house. No phase change occurs upon reflection from the mountain. What minimum ...

Thanks for the help with my previous problems. The acceleration to gravity on the moon is 1.6m/sec^2. If a rock is dropped into a crevasse, how fast it will be going just before it hits bottom 30 sec later? How far below the point of release is the bottom of the crevasse? If ...

Huh?
You can not find the forces or acceleration without more information. The only thing you can use is the First Law, conservation of momentum, which will give you final speed if they stick together. (1/3 the original speed) To answer questions about force and acceleration, you ...

You see an optical illusion of an ever-upward spiral staircase. The climber trudges up and up and never gets anywhere, going in circles instead. Suppose the staircase is provided with a narrow ramp, allowing the tired stair-climber to push a wheelbarrow up the stairs. The ...
