Explanation:
Formula for number of images formed by two plane mirrors incident at an angle θ is n = 360∘θ. If n is even, the number of images is n-1, if n is an odd number of images.
Force = (mass) x (acceleration)
5 N = (9 kg) x (acceleration)
Divide each side
by 9 kg : 5 N / 9 kg = acceleration
Acceleration = (5/9) kg-meter/sec²-kg
= 0.555... m/s² .
