Answer: 6067.5 N
Explanation:
Work = Change in Energy. To start, all of the energy is kinetic energy, so find the total KE using: KE = 1/2(m)(v^2). Plug in 1980 kg for m and 15.5 m/s for v and get KE = 237847.5 J.
Now, plug this in for work: Work = Force * Distance; so, divide work by distance to get 6067.5 N.
Answer:
They are gaining energy, can move and slide past each other.
Explanation:
Because as ice melts, the molocules gain energy/heat which warm them up and are able to slide/move apart from each other.
