A man drops a rock into a well. (a) The man hears the sound of the splash 2.96 s after he releases the rock from rest. The speed of sound in air (at the ambient temperature) is 336 m/s. How far below the top of the well is the surface of the water? m (b) If the travel time for the sound is ignored, what percentage error is introduced when the depth of the well is calculated? %

A scuba diver is under the water as pictured below. The diver shines a laser at the surface of the water initially at 55.0° from the surface (and 35° from the normal). For water, n = 1.33 and for air, n = 1.00. (a) What is the angle of the refracted ray in the air? (b) What angle should the light be moved to in order to achieve the critical angle for total internal reflection? There is a drone above...

A boat capable of making 6.0 km/h in still water is used to cross a river flowing at speed of 4.0 km/h. The boat is directed (from the perpendicular to the shore) in such a way that its resulting motion is straight across the river. At what angle (in o) must the boat be directed? What is the resultant speed relative to the shore?

A catapult on a cliff launches a large round rock towards a ship on the ocean below. The rock leaves the catapult from a height H = 34.0 m above sea level, directed at an angle above the horizontal with an unknown speed v0. The projectile remains in flight for 6.00 seconds and travels a horizontal distance D = 181 m. A) Assuming that air friction can be neglected, calculate the value of the angle (in degrees). B) Calculate the...
