Using the laws of conservation of energy and momentum, show that the ratio of the final velocities in terms of m1 and m2 is given by:

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.

conservation of mass

mass before something happens = mass afterwards

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
