It’s that or Fn Im pretty sure
Answer:
D)80/10 × 5 × 10^-4 N m^-2
Explanation:
this is the answer that was on my assignment
Acceleration = (change in speed) divided by (time for the change)
Change in speed = (50 km/h)-(30 km/h)
Change in speed = 20 km/h
Acceleration = (20 km/h) / (4 h)
Acceleration = 5 km per hour-squared

Hi there!
Recall Newton's Second Law:
∑F = Net force (N)
m = mass (kg)
a = acceleration (m/s²)
We are already given the mass and acceleration, so we can plug these values into the equation:
∑F = 1600 · 4.5 = 7200 N
