A certain amount of force produces an acceleration of 8 M/S2 square on an object of mass 750 gram what would be the mass of another object on which the same force produces an acceleration of 12m/S2 there what acceleration this force produced if the two bodies are tied together

Expert Answer:

mass of 1st object, m1 = 750 g = 0.75 kg 
acceleration produced on 1st object, a1 = 8 m/s2 
 
Thus, force acting on this object, F = mass × acceleration = 0.75 × 8 = 6 N
 
Now, it's given that the same force is acting on another object and produces the acceleration of 12 m/s2 
Hence,
 F = 6 N 
a2 = 12 m/s2 
m2 = ?
Thus,
 
m2 = Force/acceleration = 6/12 = 0.5 kg 
Thus, the mass of another object is 0.5 kg 
 
Now if these two objects are tied together and same force acts on them then - 
Total mass will be, m = m1 + m2 = 0.75 + 0.5 = 1.25 kg 
Force = 6 N 
Acceleration produced on objects tied together = Force/ mass
thus,
a = 6/1.25 = 4.8 m/s2
