Answer:
During a total lunar eclipse, the moon and sun are on the exact opposite sides of the Earth, leaving the moon entirely in the Earth's shadow. During a partial lunar eclipse, only part of the moon is in the Earth's shadow.
Explanation:
If net external force acting on the system is zero, momentum is conserved. That means, initial and final momentum are same → total momentum of the system is zero.
Newton's second law of motion:
F=ma
You convert from km/h to m/s by dividing by 3.6:
Then a is:
Then:
F=(980)(2.8)=2744 N
