Speed=0.3*100=30m/s
speed=0.1*50=5m/s
frequency=20/0,5=40HZ
frequency=80/0.2=400HZ
frequency=120/0.4=300HZ
wavelength=340/440=0.77m
wavelength=340/880=0.39m
wavelength=250/400=0.63m
speed=2*50=100m/s
speed=0.5*100=50m/s

Answer:
166 m
Explanation:
t = Time taken
u = Initial velocity = 9.8 m/s
v = Final velocity
s = Displacement
g = Acceleration due to gravity = 9.80 m/s² = a
Equation of motion

Time taken to go up is 1 second and to go down will also be 1 second
Total time the rocket is up in the air is 2 seconds


The distance the train will travel is 166 m
