what is the displacement of the cross country team if they begin at the school run 10 miles and finish back at the school?

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers

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
