An object of mass 1 kg travelling in a straight line with a velocity of 10 m s-1 collides with, and sticks to, a stationary wooden block of mass 5 kg. Then they both move off together in the same straight line. Calculate the total momentum just before the impact and just after the impact.
Step 1 of 3 Initial momentum of object=m1 v1=1 X 10 =10 kgms-1 Step 2 of 3 Initial momentum of wooden block=m2 v2= 5 × 0 =0 Step 3 of 3 Total momentum=momentum of object+ momentum of wooden block Total momentum=10+0=10 kgms-1 Final Answer Total momentum just before impact is 10 kgms-1.
