Answer:
South = 1.5m
West =4.2m
Explanation:
Kindly see attached a rough draft of the situation
Step one
Given data
From the sketch the direction of the player is along the resultant of the triangle, corresponding to the Hypotenuse
Step two:
Hence for an opponent to tackle him towards the south, he must be at
sin θ= opp/hyp
sin 20=x/4.5
x=sin 20*4.5
x=0.342*4.5
x= 1.5m
Also, for an opponent to tackle him towards the south, he must be at
cos θ= adj/hyp
cos 20=y/4.5
y=cos 20*4.5
y=0.93*4.5
y= 4.2m
Answer:
17.55 m/s
Explanation:
The number of times a wave will pass through a particular point is called frequency so, here the frequency is 3 Hz = f
The distance which is measured between two troughs or crests in a wave is called wavelength so, here the wavelength is 5.85 m =
Velocity is given by
The propagation speed of the waves is 17.55 m/s
