Answer 1

9514 1404 393

Answer:

  A. 20·60

Step-by-step explanation:

I often like to keep the units with the numbers, especially in Physics problems. This helps make sure the math is being done correctly.

  W = F·D

  W = (60 N)(20 m) = 60·20 N·m = 60·20 (kg·m/s²)(m) = 60·20 kg·m²/s²

  = 20·60 J
