Question

An 8000 kg truck starts iff from rest and reaches a velocity of 18 m/s in 6 s. What is the truck's acceleration and how much momentum does it have reached this final velocity?

Answer 1

Step-by-step explanation:

a = Δv/t = (18 m/s - 0) / 6 s = 3 m/s²

Momentum = P = mv = (8000 kg)(18 m/s) = 144,000 kg·m/s
