First, we need to calculate the momentum of the pellet before it hits the glider.

Given:
Mass of pellet (m1) = 0.45g = 0.00045kg
Initial velocity of pellet (u1) = 0 m/s (as it is fired from rest)

Momentum of pellet before hitting the glider:
p1 = m1 * u1 = 0.00045kg * 0 = 0 kg m/s

Now, we need to calculate the velocity of the glider after the pellet hits it.

Given:
Combined mass of glider and target (m2) = 643g = 0.643kg
Distance moved by glider (s) = 50cm = 0.5m
Time taken for glider to move (t) = 3.8s

Using the equation of motion:
s = (u2 + u1) * t / 2
0.5 = (u2 + 0) * 3.8 / 2
u2 = 0.5 * 2 / 3.8
u2 = 0.2632 m/s

Now, we can calculate the velocity of the pellet after hitting the glider using the principle of conservation of momentum:

Initial momentum = Final momentum
m1 * u1 = (m1 + m2) * u2
0 = (0.00045 + 0.643) * u2
u2 = 0 / 0.64345
u2 = 0 m/s

Therefore, the velocity of the pellet after hitting the glider is 0 m/s.

Momentum of pellet and glider was conserved.
Momentum=mass x velocity
Momentum of pellet before firing=0 as it is at rest
Momentum of pellet after firing=0.45g(V)
Momentum of glider and target before firing=0(at rest)
Momentum of glider and target after firing=(643+0.45)g(u)
=643.45gu
Momentum of pellet=momentum of glider and target
0.45gV=643.45gu
V=(643.45gu)/0.45g
Velocity of pellet(V)=1430u

Therefore since u=50cm/3.8s
V=1430(50/3.8)
V=18842.1cm/s
