Question

A cracker of mass 320 g explodes into two pieces of equal mass. Show that these two pieces of the cracker fly in opposite directions.

Answer 1

MARK ME AS BRAINLIEST

The total momentum =constant

P = M  

for V₀

M = 320 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.
