A certain force applied to mass m, gives it an acceleration of 15 m/s The same force is applied - Science - Force and Laws of Motion

Question

A certain force applied to mass m, gives it an acceleration of 15
m/s The same force is applied on m, to give it acceleration of 10
m/s2, if the two masses are fixed together and the same force is
applied to the combination, then the acceleration will be

Dear Student,
â€‹F = m a
Case 1
a = 15 m/s2
F = m 15
m = F/15
Case 2
a = 10 m/s2
F = M 10
M = F /10

Case 3
F = (m + M) a
F = (F/15 + F/10) a
F = (2F+3F)/30 a
F = 5F/30 a
a = 6 m/s2
