Question

A bullet having a mass of 10 and
moving with a speed of 1.5 m/s,
penetrates a thick wooden plank of
mass 900 g. The plank was initially
at rest. The bullet gets embedded in
the plank and both move together.
Determine their velocity.​

Answer 1

Answer:

0.01648m/s

Explanation:

here we know that

m1v1= m2v2

here m1 = 10g and v1 = 1.5 m/s

and m2= 900 + 10 = 910 g and v2 we have to find

10 * 1.5 = 910 *v2

15= 910 *v2

v2= 0.01648 m/s
