Answer» 5 kg is the right answer. 5Kg. . Weight (W) = 49 N acceleration due to gravity (g) = 9.8 m/s^2 Mass (m) = ? We know, W = m * g or, m = W / g or, m = 49 / 9.8 Therefore, mass (m) = 5 kg 5kg right answer this question We know that, weight= Mass × acceleration due to gravity.let weight = w let mass = m let acceleration due to gravity = g w= m×g so m = w÷g w= 49g= 9.8 m/s^2 m= 49÷9.8 m= 5kg hence, mass is 5 kg |
