Answer:
Problem no. 1:Determine the acceleration when a 24-N net force is applied to a 12-kg object.
Given:
[tex]a = {?}^{} \\ f = 24n \\ m = 12 - kg[/tex]
Find:
The acceleration of a 12kg object when a 24n of force is applied.
Formula:
[tex]f = ma[/tex]
Solution :
[tex] \frac{f}{m} = \frac{ma}{m} \\ a = \frac{f}{m} \\ a = \frac{24n}{12kg} \\ a = 2m | s {}^{2} [/tex]
The acceleration of the object is 2m/s²
========================================
Problem no. 2: A net force of 30 N is exerted on an encyclopedia to cause it to accelerate at a rate of 5 m/s2. Determine the mass of the encyclopedia.
Given:
[tex]a = 5 m/s2 \\ m = {?}^{} \\ f = 30n[/tex]
Find:
The mass of the encyclopedia when a 30 N is exerted on an encyclopedia to cause it to accelerate at a rate of 5 m/s².
Formula :
[tex]m = f/a[/tex]
Solution:
[tex]m = f/a \\ m = 30n/5m/s {}^{2} \\ m = 6kg[/tex]
The mass of the encyclopedia is 6kg.
