Question

- A sphere of mass 10 kg makes a perfectly inelastic collision with another sphere initially at rest and
the two move together with a speed equal to half the original speed of 10 kg sphere and in the same
direction. Find the mass of second sphere. (10kg)


Please solve this on the paper and don't post irrelevant answer guys be humans ​

Answer 1

Answer:

m = 10 kg

Explanation:

p1= 10 u

p2 = (m1+ m2)v

= (10+ m) u/2

p1=p2

10u = (10+m) u/2

20=10+m

m = 10 kg
