Answer:
Step-by-step explanation:
acceleration, a = 20 m/s^2
initial velocity, u = 0 since it starts from rest
final velocity, v = 400 m/s
v = u + at
400 = 0 + 20 t
400 = 20 t
t = 400 / 20
<u><em>t = 20 sec</em></u>

Step-by-step explanation:
You can put this solution on YOUR website!
2g-m=5-gh solve for g
2g+gh=5+m
g(2+h)=5+m
g=(5+m)/(2+h)
