A force of 100 N , acting on a mass m1 produces an acceleration of 5 m/s2.The same force when applied to mass m2, gives it an accleration of 40 m/s2.What accleration would the same force produce,when both masses are tied together ?

The following steps need to be followed in order to solve the query:
 
Step 1) Force and acceleration for masses m1 and m2 are given. So, the easiest thing to do is to find both the masses. Use the formula F = ma to find m1 and m2. They will be given by F/a.
 
Step 2) Now the masses are tied, so add m1 and m2 to find M.
 
Step 3) Use the formula F = ma again to find final acceleration 'a' by doing F/M.

Two hockey players of opposite teams, while trying to hit a hockey ball on the ground collide and immediately become entangled. One has a mass of 60 kg and was moving with a velocity 5.0 m s–1 while the other has a mass of 55 kg and was moving faster with a velocity 6.0 m s–1 towards the first player. In which direction and with what velocity will they move after they become entangled? Assume that the frictional force acting between the feet of the two players and ground is negligible.
