Question

A certain force applied to a body A gives it an acceleration of
10 m/s^2 The same force applied to body B gives
it an acceleration of 15 m/s^2 If the two bodies are joined
together and the same force is applied to thecombination, the
acceleration will be(1) 6 ms2 (2) 25 ms2 (3) 12 5 ms2 (4) 9 ms2

m1 is themass of body Am2 is the mass od body BForce = mass
accelerationf = m1×10f = m2×15 m2×15 = m1×10m1m2 = 32f = (m1+m2)a3m1×10 = (m1+m2)a310m1 =(m1+23m1)a310m1 = 53m1a3a3 = 6 m/s2

A certain force applied to a body A gives it an acceleration of 10 m/s^2. The same force applied to body B givesit an acceleration of 15 m/s^2. If the two bodies are joined together and the same force is applied to thecombination, the acceleration will be(1) 6 ms2 (2) 25 ms2 (3) 12.5 ms2 (4) 9 ms2
