Question

i. a standard baseball has a mass of 145 g. what is the weight of a standard baseball? 1.42 n 1420 n 14.8 n 0.0148 n

Explanation:

Step1: Convert mass from grams to kilograms

Given mass \(m = 145\space g\). Since \(1\space kg=1000\space g\), then \(m=\frac{145}{1000}\space kg = 0.145\space kg\).

Step2: Use the formula \(F = mg\) (where \(g = 9.8\space m/s^{2}\))

Substitute \(m = 0.145\space kg\) and \(g=9.8\space m/s^{2}\) into the formula. So \(F=(0.145\space kg)\times(9.8\space m/s^{2})\).
Calculate \(0.145\times9.8 = 1.421\approx1.42\space N\)

Answer:

1.42 N
