3. Sound caused by an explosion on the ocean's surface travels vertically downward to an underwater mountain and is reflected back to a microphone at
the surface. If this takes 11.6 s to occur and sound travels at h1450 m/s in water,
what is the depth to this mountain?

hello there!

your answer is a “generator”

a generator does not create energy but instead it transforms it.

it’s basically a motor working in reverse.

change tension

grav force prop 1/r squared 2r all squared is 4rsquared 1/4rsquared quartered

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
