what is the acceleration of an 18 kg mass pushed by a 9 N force?

a = F/ma = 9/18a = 1/2thus the acceleration is 0.5 m/s2

We know, force(f) = (mass×acceleration) = (m×a) N. ...(1)Here, f = 9 N        m = 18 kg.                                                                                                 Since, f = m×a. Therefore, a = f ÷ m = 9 ÷ 18 = 0.5 m/s². Ans. Required acceleration = 0.5 m/s².
