using the formula W= mg what is the answer if a baseball is 143 grams

To find the weight of an object, you would need to multiply the mass of the object by the acceleration due to gravity (9.8 m/s^2).

Given:
Mass (m) = 143 grams = 0.143 kg
Acceleration due to gravity (g) = 9.8 m/s^2

Using the formula:
W = m * g
W = 0.143 * 9.8
W = 1.4014 kg m/s^2

Therefore, the weight of a baseball that is 143 grams is approximately 1.4014 kg m/s^2.
