Question

A bullet of mass 100g is fired towards a stationary wooden block of mass 900g. The bullet hits the block with speed 50ms-1 and sticks into it. Find the final velocity of the combination.

Answer 1

Hi,

Here is your answer

Given:

Mass of bullet(m1)=100g=0.1kg

Velocity of bullet(v1)=50m/s

Mass of wooden block(m2)=900=0.9kg

To find:

Final velocity of the system(v)

Solution:

We know that mometum is conserved.

That is,

Initial momentum=Final momentum

m1×v1=(m1+m2)v

Substitute the given datas in the equation

We get,

0.1×50=(0.1+0.9)v

v=5m/s

Hope this helps you.

Answer 2

Answer:

v = 5m/s answer take care friends
