Answer:
The answer is 54.18 meters.
Explanation:
Fk = -mg + N cos (20) = 0
Fr = N sin (20) ( frictional force)
Fr = m (a) where as a = v²÷r
By putting in the values..
N = mg÷ cos (20)
r = v²÷ g tan (20) (radius equation)
= 13.89²÷ 9.81(tan 20) (gravitational force = 9.81 m/s²)
r = 54.18 meters.
10-7= 3 3+7=10 because if u subtract 10 by 7 gives u 3
Answer:
Final answer is 
.
Step-by-step explanation:
Given that slope of the line is m=3
Plug the given point (4,-1) and the slope m=3 into point sloep formula:
Which looks like slope intercept form of line y=mx+b
Hence final answer is .
Vx = axis of symmetry
Vx=-b/2a
b=4 and a=1
Vx=-4/2
Vx=-2
therefore, the AOS is x= -2
