A bullet of mass 10g moving with 300m s
Asked by admin @ in Physics viewed by 304 People
A bullet weighing 10g and moving with a velocity 300m/s strikes a 5kg block icecrran
Answered by admin @
This is a question on momentum.
The initial velocity for the block of ice is 0.
This is because the block of ice is at rest.
Momentum = mass × velocity
By law of conservation of momentum :
Initial momentum = final momentum
Initial momentum :
(10/1000 × 300 + 0 × 5) = 3
Final momentum :
(5 + 0.01) V = 5.01V
By law of conservation of linear momentum :
5.01V = 3
V = 3/5.01 = 0.5988
V = 0.6 m/s
The ice moves at :
= 0.6 m/s
