Answer:
A) mr = 100 kg
B) Fr = 210N
C) Ft = -199.5N
Explanation:
By conservation of the momentum:
mt*Vo = (mr + mt) * Vf Solving for mr:
mr = mt*Vo / Vf - mt = 100 kg
The average force on the receiver:
mr *(Vf - 0) = Fr * Δt Solving for Fr:
Fr = 210 N
The average force on the tackler:
mt * (Vf - Vo) = Ft * Δt Solving for Ft:
Ft = -199.5 N
The vertical displacement of the wave is measured from
the equilibrium to the crest and is called the amplitude.
Static electricity is the build up of electrical charges on the surface of some object or material.
Static electricity is usually created when materials are pulled apart or rubbed together causing positive (+) charges to collect one material and negative (-) charges on the other surface.
It is called static because the charges remain in one area for a while rather than moving or flowing to another area.
Results from static electricity may be sparks, shock or materials clinging together.
