A force of 100 N produces an acceleration of 100m/s 2 and 200 m/ s 2 in an object A and an Object B respectively. What would be the acceleration if both the object are combined as one. What should be the force applied on each of the object to produce the same acceleration?

Given, force F = 40N. acceleration a = 8m s We know that F=ma. When another object of same mass is tied to given object then we get change in mass as m' = m + m = 2m. Now if a force F is required to produce same acceleration again, then F = m'a = 2ma F F 2ma ma = 2 or F2F = 2 x 40 N = 80 N
