Answer:
arrangement 2
Explanation:
arrangement 1's spring would broke idek
He should a step-up transformer with k=220/120=1.83 so output coil must have 240*1.83=440 turns
I think you would use F = ma
F = 65*10
F = 650N
(The 10m/s is from acceleration due to gravity)
A 'displacement' always consists of a magnitude and a direction. The two cars you just described have displacements with the same magnitude ... 5 km. But if they didn't both drive in the same direction, then their displacements are different.
Remember:
-- 10 m/s² up and 10 m/s² down are different accelerations
-- 30 mph East and 30 mph West are the same speed but different velocity.
-- 5 km North and 5 km South are the same distance but different displacement.
F = 52000 N
m = 1060 kg
a= F/m = 52000 N/1060 kg = 49.0566 m/s^2
