It's number three on your worksheet. ;)
Answer:
21 m/s.
Explanation:
The computation of the wind velocity is shown below:
But before that, we need to find out the angles between the vectors
53° - 35° = 18°
Now we have to sqaure it i.e given below
v^2 = 55^2 + 40^2 - 2 · 55 · 40 · cos 18°
v^2 = 3025 + 1600 - 2 · 55 · 40 · 0.951
v^2 = 440.6
v = √440.6
v = 20.99
≈ 21 m/s
Hence, The wind velocity is 21 m/s.
Answer:
im pretty sure the answer is c please mark me brainliest
Explanation:
answer 689910
M x G x H
mass = 77
G= 9.8
Meter = 915 this is the height
77 x 9.8= 754.6
754.6 X 915 = 689910 J
