1.

Thus, the weight of the body 15 491Sample Problem 2. What is the mass of an object whose weight is 49 newtons ?

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
