Question

A dart, of mass 10 g, moving with a velocity of 100 ms-1 , strikes a wooden block of mass 990 g and gets embedded in it. Find the velocity with which the combined mass would move. Also find the loss in K.E. during this collision.​

Answer 1

Answer:

hope it helpful to you

answer is 49.5

Answer 2

Answer:

The velocity = 1.091m/s and loss in K.E during this collision = 49.4J

Explanation:

Given:-

The mass of the bullet $m_{1}$ = 10g = 0.01 kg

The mass of the wooden block $m_{2}$ = 900g = 0.9kg

Let the final velocity acquired by the block be v m/s

initial velocity of dart $u_{1}$ = 100m/s

initial velocity of wooden block $u_{2}$ = 0 m/s
