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