1. Understand the Forces:
* Weight (Force of Gravity): The baby's weight acts downward. Calculate it using:
* Weight (W) = mass (m) * acceleration due to gravity (g)
* W = 8 kg * 9.8 m/s² = 78.4 N
* Applied Force: The upward force pulling the baby is 150 N.
2. Find the Net Force:
* The net force is the difference between the upward force and the downward force (weight).
* Net Force (F_net) = Applied Force - Weight
* F_net = 150 N - 78.4 N = 71.6 N
3. Apply Newton's Second Law:
* Newton's Second Law states: F_net = mass * acceleration (a)
* Rearrange to find acceleration: a = F_net / mass
* a = 71.6 N / 8 kg = 8.95 m/s²
Therefore, the acceleration of the 8 kg baby is 8.95 m/s² upward.
