Answer:
Impulse is related to momentum because impulse is a term that describes object's change in momentum. The measurable quantity of momentum changing is called impulse.
Answer:
Explanation:
18 km/hr(1000 m/km) / (3600 s/hr) = 5 m/s
36 km/hr = 10 m/s
v² = u² + 2as
a = (v² - u²)/2s
a = (10² - 5²)/2(1000) = 0.0375 m/s²
v² = 10² + 2(0.0375)(1000)
v² = 175
v = 13.22875... ≈ 13 m/s ≈ 48 km/hr
v = u + at
t = (v - u) / a
t = (10 - 5)/0.0375 = 133.333... 133 s
t = (13.22875 - 10) / 0.0375 = 86.1 s
