Question

12. A cracker of mass 100 g explodes into 2 pieces of equal mass.Show that these two Pieces of cracker fly in opposite directions.​

Answer 1

Answer:

The total momentum =constant

P = M

for V₀

M = 100 g

V₀ = 0. So, P = 0.

and

After the explosion,

P = m1 x V1 + m2 x V2

where m1 = m2 = M / 2. Putting the value

(M / 2) x V1 + (M / 2) x V2 = 0

V1 + V2 = 0

V1 = - V2,

so they fly in opposite directions.
