InterviewSolution

1.	A body is initially at rest when we apply a constant force of 50 N it moves a distance of 20 m in 2 seconds find the mass of the body. please explain step by step.
Answer» 5 kgExplanation:F = maConstant force means constant acceleration.We can FIND a using the displacement FORMULA:s = UT + 0.5 at^2u = 0 since object is INITIALLY at rests = 20 metrest = 2 seconds20 = 0 + 0.5a(2)^220 = 2aa = 10 m/s^2m = F/a = 50/10m = 5 kg
