A heliocentric system is a sun-centered
Answer:
0 Newtons
Explanation:
The velocity of the object does not change, it is a constant 54 km/hr. When velocity does not change, acceleration is zero. Using the formula Force = mass x acceleration, we find:
mass = 1200 kg
acceleration = 0
F = (1200)(0) = 0
The speed of an object at rest is 0 m/s. We can use logic to figure this out. Hope this helps!
