Answer:
v= 0.2 m/s
Explanation:
Given that
m₁ = 50 kg
m₂ = 100 g = 0.1 kg
u =10 0 m/s
If there is no any external force on the system then the total linear momentum of the system will be conserve.
Initial linear momentum = Final momentum
m₁u₁ + m₂ u₂ =m₂ v₂ +m₁v₁
50 x 0 + 0.1 x 100 = 50 v + 0
0+ 10 = 50 v
v= 0.2 m/s
Therefore the recoil speed will be 0.2 m/s.

Astronomers can measure a star's position once, and then again 6 months later and calculate the apparent change in position. The star's apparent motion is called stellar parallax. The distance d is measured in parsecs and the parallax angle p is measured in arcseconds.
I hope this helps!
KE = (1/2)·(mass)·(speed)²
It doesn't matter whether the object is in a car, on a boat,
falling, on a conveyor belt, or being carried by ants.
KE = (1/2)·(40 kg)·(2 m/s)²
KE = (20 kg)·(4 m²/s²)
KE = 80 kg-m²/s²
KE = 80 Joules
That's actually a lot easier than finding total <u><em>distance.</em></u>
To find displacement, you only have to know where the trip started from, and where it ended. It doesn't matter what route was followed to actually travel from the start to the finish. The displacement is the straight-line distance and direction between those two points.
