Decreasing the air temperature Question 4 (1 point)
The speed of sound in a certain metal
block is 2.00 m/s. The graph shows the
amplitude(in meters) of a wave traveling
through the block versus time (in
milliseconds). What is the wavelength of
this wave

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

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
