1. The problem statement, all variables and given/known data A force F applied to an object of mass m1 produces an acceleration of 3.00 m/s2. The same force applied to a second object of mass m2 produces an acceleration of 1.30 m/s2. Find the ration of m1/m2 If m1 and m2 are combined, find their acceleration under the action of the force F. 2. Relevant equations F=ma 3. The attempt at a solution for the first part i just used F=m1x3 and F=m2x1.3 and put them together like m1x3=m2x1.3 and used 3/1.3 but that didnt work
it would be 1.3/3 no 3/1.3 because if you have m1(3)=m2(1.3) then you divide by m2 and have m1(3)/m2=1.3 then divide by 3 and get m1/m2=1.3/3
F = m1 a1 F = m2 a2 F/a1 = m1 and F/a2 = m2 F = (m1 + m2) x, x be the acceleration of the combined mass x = F / (m1 + m2) x = F / (F/a1 + F/a2) x = 1 / (1/a1 + 1/a2) x = a1.a2 / (a1 + a2)
