☃ First of all we have to calculate frictional force by using below equation :
→ F = μR
→ F = 0.2 × 5 × 10
→ F = 10 N
- Hence,the frictional force (F) is 10 N.
☃ But we know that frictional force is acting on opposite direction of the motion :
⇏Net force = 15 - 10
⇏Net force = 5 N
- Hence,the net force is 5 N.
☃ By using Newton's second law we get :
- Let the required acceleration produced by the block be 'a'.
➝ Force = mass × acceleration
➝ 5 = 5 × a
➝ a = 5 ÷ 5
➝ a = 1 m/s²
- Hence,the acceleration produced by the resultant force acting on the block is 1 m/s².
