The final velocity of the red barge in the collision elastic is 0.311 m/s when it collides with blue barge pf mass 1000000 kg.
Final velocity(v3) of the red barge is calculated by following formula
m1×v1+ m2×v2= (m1+m2)v3
Substituting the value of m1= 150000 kg, v1= 0.25 m/s, m2= 1000000 kg, v2= 0.32 m/s
150000 × 0.25+ 1000000×0.32= (150000+1000000)×v3
37500+ 320000= 1150000×v3
357500= 1150000×v3
v3= 0.311 m/s
<h3>What is elastic collision velocity? </h3>
- The velocity of the target particle after a head-on elastic impact in which the projectile is significantly more massive than the target will be roughly double that of the projectile, but the projectile velocity will remain virtually unaltered.

Answer: 52.53
Explanation:
m*g = 5.36k * 9.8N/kg = 52.53 N. = Wt.
of object.
a. KE = 0 J. = Initial KE
V^2 = Vo^2 + 2g*h
V^2 = 0 + 19.6*1 = 19.6
V = 4.43 m/s.
KE = 0.5m*V^2 = 2.68*4.43^2 = 52.59 J.
b. V^2 = Vo^2 + 2g*h
V^2 = 4.43^2 + 19.6*1 = 39.22
V = 6.26 m/s.
KEo = 2.68*4.43^2 = 52.59 J.
KE = 2.68*6.26^2 = 105 J.
