The acceleration of gravity on the earth is 9.80 m/s 2. If a person weighs 335 N, what is his/her mass?
padilas [110]

Answer:

About 34.18kg

Explanation:

Using F=ma, you know that the force that an object exerts can be found by multiplying the mass and the acceleration. Therefore, you can find the mass with the formula m=\dfrac{F}{a}. Plugging in the values you were given, m=\dfrac{335}{9.80}\approx 34.18kg. Hope this helps!
