1. Identify the Forces:

* Force of gravity (weight): This acts downward and is calculated as:

* Weight (W) = mass (m) * acceleration due to gravity (g)

* W = 50 kg * 9.8 m/s² = 490 N

* Applied force: This acts upward and is given as 600 N.

2. Calculate the Net Force:

* The net force is the difference between the upward force and the downward force:

* Net force (F_net) = Applied force - Weight

* F_net = 600 N - 490 N = 110 N

3. Apply Newton's Second Law:

* Newton's Second Law states: F_net = mass * acceleration (a)

* We can rearrange this to solve for acceleration:

* a = F_net / mass

* a = 110 N / 50 kg = 2.2 m/s²

Therefore, the acceleration of the cement block is 2.2 m/s² upwards.
