Answer:
4.9
Explanation:
Velocity half second before maximum height = Velocity half second after maximum height (Return journey)
For downward journey :
Initial velocity u=0 m/s
We have g=9.8 m/s
Time t= ½s
s
Thus velocity after half second v=u+gt
v=0+9.8× ½ =4.9m/s
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
