Which of the following statements is incorrect?

a) it is not possible to know the exact location of an electron and its exact energy simultaneously.
b) the energies of an atom's electrons are quantized.
c) quantum numbers define the energy states and the orbitals available to an electron.
d) the behavior of an atom's electrons can be described by circular orbits around a nucleus.
e) electrons have both wave and particle properties.

we need to know the time interval during which the force acts. impulse of force = momentum change

i think it would be 5

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
