Question

3. What is the WEIGHT of an object if it

has a mass of 12kg?

4. What is the MASS of a golfball if it has
a weight of 1.5N1?

5. What is the MASS of a bowling ball if it has a
weight of 71.15N 1?

help?

Answer 1

Weight = mass * gravity
W = mg

gravity (near surface of earth) = 9.8m/s^2

Therefore, W = 9.8m.

Use this equation to solve for each unknown variable.

For 3) W = 9.8(12) = 117.6N.

Unit for mass is kg, unit for weight is N.
