Answer:
see below
Step-by-step explanation:
cos(420°) = cos 60 = 1/2
sin(450°) = sin 90 = 1
9514 1404 393
Answer:
yes
Step-by-step explanation:
The height that would be allowed with a ramp 43.5 feet long is ...
h = (43.5 ft)·sin(4.8°) ≈ 3.64 ft
The proposed height is less than 3.64 ft, so the ramp angle is less than 4.8°.
__
The ramp angle is actually arcsin(3/43.5) ≈ 3.95°, which is less than 4.8°.
Answer:
v = 16.
Step-by-step explanation:
This is one of the equations of motion when acceleration is constant.
v = 6 + 2*5
= 16.
Answer:
