Momentum before the hit:
p = mv = 0.01 * 300 + 1 * 0
Momentum after the hit:
p = 0.01 * 150 + 1 * v
Momentum is conserved:
0.01 * 300 = 0.01 * 150 + v
3 = 1.5 + v
v = 1.5
The velocity of the block after the collision is 1.5 m/s.
<span>v=40 <span><span>cm</span>s</span> speed of wave</span>
<span>λ=8 cm wavelength</span>
<span>f=? frequency of wave</span>
<span>v=λ⋅f</span>
<span>40=8⋅f</span>
<span>f=<span>408</span></span>
<span>f=5 <span>s<span>−<span>1 is the answer </span></span></span></span>
The answer to this is
<span>A mass on a spring will oscillate vertically when it is lifted and released. The gravitational potential energy increases from a minimum at the lowest point to a maximum at the highest point. ... The total mechanical energy at those points is the sum of the elastic and gravitational potential energies.</span>
Hope This Helps!

Protons and neutrons have similar mass
Electrons are smaller then a proton or a neutron
