Answer:
18.60 m/s
Explanation:
Original momentum = mv = 4000 with m = 115
after collision m = 115 + 100 = 215 kg
but the total momentum is still the same (conserved)
4000 = 215 v shows v = 18.60 m/s

Explanation:
Answer:
2.It has twice the KE
Explanation:
Given that
m ₁ = 2 m₂
Height = h
For mass m ₁ :
By using energy conservation
m ₁ g h = KE₁
KE₁ = m ₁ g h
For mass m ₂ :
By using energy conservation
m ₂g h = KE₂
KE₂= m ₂ g h
m ₁ = 2 m₂
KE₁ = m ₁ g h
KE₁ =2 m₂ g h
KE₁ = 2 KE₂
The kinetic energy for the massive marble is twice the other one marble.
Therefore the answer will be 2.
