Question

An object of
mass 1kg
travelling in straight line with a
velocity af 10m/s collides with, and stick to a stationary wooden blocks of
mass 5kg. Then they both move
off together in the
straight line Calculate the total me
Calculate the total momentum just before
the impact and just after the impact. Also, calculate the velocity
of the combined objects.
​

Answer 1

m=1kg

u=10m/s

Momentum of the system of two masses before collision--

1×10+5×0

=10 kg m/s

Momentum of the system of two masses after collision---

(m+M)V

(1+5)V

=6V

On applying conservation of momentum,we get----

6V=10

V=10/6

V=5/3m/s
