Answer:
Explanation:
We will use the KE equation you wrote here and fill in what we are given:
and isolating the m:
which gives us
m = .50 kg
The motion would not move at all, because the forces that are acting on it are equal and are acting in opposite directions
Photovoltaic cells are well known for their ability to convert solar energy (1) into electrical energy.
Formula for net force: force= mass x acceleration
Answer: 480 kJ
Explanation: Energy = power · time
E = Pt = 4000 W · 120 s = 480 000 J
