A 3D printer is set to a print speed of 50 mm/s and acceleration of 800 mm/s². If the printer starts from rest, how long will it take to reach the print speed?
A0.0625 seconds
B40 seconds
C800 seconds
D50 seconds
Step-by-Step Solution
Solution:
  1. Step 1: Use formula time = speed / acceleration

    Time to reach speed = 50 mm/s ÷ 800 mm/s² = 0.0625 s.
  2. Step 2: Calculate and confirm units

    Units cancel correctly, result is in seconds.
  3. Final Answer:

    Time to reach speed is 0.0625 seconds -> Option A
  4. Quick Check:

    Time = speed/acceleration = 0.0625 s [OK]
Quick Trick: Time to speed = speed divided by acceleration [OK]
Common Mistakes:
  • Multiplying instead of dividing
  • Mixing units or ignoring units
