Naoki's bicycle has a mass of 10 kg. If Naoki sits on her bicycle and starts pedaling with a force of 168 N, causing an accelera

White raven [17]

Answer:

50 kg

Explanation:

Data:

Mass of bicycle = 10 kg

F = 168 N

a = 2.8 m/s²

Calculation:

F = ma Divide each side by m, Then

m = F/a

= 168/2.8

= 60 kg

m = mass of bicycle + Naoki's mass. Then

60 = 10 + Naoki's mass Subtract 10 from each side

Naoki's mass = 50 kg

<u>Step 1: Define</u>

[Given] 1.00 × 10²⁴ atoms Mn

<u>Step 2: Identify Conversions</u>

Avogadro's Numer

[PT] Molar Mass of Mn - 54.94 g/mol

<u>Step 3: Convert</u>

[DA] Set up: $\displaystyle 1.00 \cdot 10^{24} \ atoms \ Mn(\frac{1 \ mol \ Mn}{6.022 \cdot 10^{23} \ atoms \ Mn})(\frac{54.94 \ g \ Mn}{1 \ mol \ Mn})$
