Total time travelled =
∴ Driver's average velocity =
I have no clue sorry maybe try applying the answers and questions then I'll answer for u
Answer:
900kg
Explanation:
Data obtained from the question include:
F = 27000N
a = 30.0m/s^2
M =?
F = Ma
M = F/a
M = 27000/30
M = 900kg
Wavelength and frequency have a reciprocal relationship. If one doubles, the other halves.
