Answer:
2.88m/s
Step-by-step explanation:
By using the law of conservation of momentum
Initial momentum = final momentum
v = is their combined velocity afterwards
Solving equation (1) for v
V = 2.88 m/s
Therefore the velocity afterward is 2.88 m/s.
Answer:
6⁸
Step-by-step explanation:
Rule of exponents:
(xᵃ)ᵇ = xᵃ*ᵇ
(6²)⁴ = 6²*⁴ = 6⁸
