Final answer:
To find the weight of a 146 gram baseball in newtons, multiply the mass in kilograms by Earth's gravitational acceleration. The resulting weight is approximately 1.43 N.
Step-by-step explanation:
To calculate the weight of an object in newtons, you use the formula W = mg, where W is the weight in newtons, m is the mass in kilograms, and g is the acceleration due to gravity (9.8 m/s² on Earth). An official Major League Baseball has a mass of roughly 146 grams, which is 0.146 kilograms. So its weight is calculated as follows:
W = (0.146 kg)(9.8 m/s²) = 1.4308 N.
Therefore, the weight of the baseball is approximately 1.43 N when rounded to two decimal places.
