Question

An object of mass 1 kg travelling in a straight line with a velocity of 10 m s–1 collides with, and sticks to, a stationary wooden block of mass 5 kg. Then they both move off together in the same straight line. Calculate the total momentum just before the impact and just after the impact. Also, calculate the velocity of the combined object

Answer 1

m1 = 1 kg        v1 = 10 m/s         
m2 = 5 kg      v2 = 0
velocity after collision  =  v

total linear momentum before the impact = total linear momentum after the impact
     m1   v1  +  m2  v2 = (m1 + m2)  v
     1 * 10 + 5 * 0 = 6 * v
       => v = 1.667  m/sec

Answer 2

HELLO FRIEND HERE IS YOUR ANSWER,,,,,,,,


Full Question: An object of mass 1 kg is found to be travelling with a velocity if 10 m/s along a straight line in turn colliding with a stationery wooden block having a mass of 5 kg. Calculate the total momentum of it just before and after the colliding is done. Calculate the total velocity of a combined system.

ANSWER :

Refer and consult to the following attachments for a detailed explanation and step by step solution with vital elaborations for certain formulas used into this query to arrive at a final conclusion that is,,,,


$\boxed{\bf{Total \: Momentum = 10 \: Kg \: m/s}}$


$\boxed{\bf{Total \: Velocity = \frac{5}{3} \: m/s}}$


HOPE IT HELPS YOU AND CLEARS THE DOUBTS TO FIND TOTAL MOMENTUM AND TOTAL VELOCITY OF THE GIVEN SYSTEM!!!!!!!
