A 90kg canon fires 100kg shell with muzzle velocity of 75m/s. Calculate the recoil velocity of the canon relative to the ground

Answer»

ANSWER:

(M1)=90kg

m2=100kg

v2=75m/s

v1=?

from principle of conservation of

linear momentum,

INITIAL momentum=final momentum

0=m1.v1+m2.v2

0=90.v1+100.75

90.v1 =-7500

v1=-7500/90

:v1=-83.33m/s

-'ve sign indicate VELOCITY of CANON

Is in opposite directions..
