Answer:
yᵢ = h
vᵢᵧ = 0
Explanation:
Let initial velocity = u
final velocity = v
height = h
acceleration due to gravity = g
Therefore fro equation of motion,
Here initial velocity is zero.
Hence, 
but since it points downward and you positive is taken in the up direction
Momentum is mass times velocity of the object
p = m • v
p = (7700 kg)(14 m/s)
p = 107809 kg m/s
In physics weight is the force exerted on a body by gravity so, the seller should have said it has a mass of 1 kg because mass is the amount of matter in an object.
<span>The key equation is going to come from Mr Planck: E=h \nu
Where h is Plancks constant; and ν is the frequency. This equation gives you the energy per photon at a given frequency. Alas, you're given wavelength, but that's easy enough to convert to frequency given the following equation:
c= lambda / nu
where c is the speed of light; λ (lambda) is the wavelength; and ν is again frequency. As soon as you know the energy of a photon with a wavelength of 550nm, you should know how many photons you would require to accumulate 10^-18J. Be careful with your units.</span>
