Answer:
Banking angle, 
Explanation:
It is given that,
Radius of the curve, r = 52 m
Speed of the car, v = 12 m/s
Acceleration due to gravity, 
Let the curved is banked at an angle of
with respect to the horizontal. It is given by :


So, the curve is banked at an angle of 15.77 degrees wrt the horizontal. Hence, this is the required solution.
Answer:
It Is violet
Explanation:
It has the shortest wavelengths and the shorter the wavelengths the higher the frequency.
Answer:
v(t) = s′(t) = −9sin(t)+9cos(t)
a(t) = v′(t) = −9cos(t) −9sin(t)
Explanation:
Given that
s = 9 cos(t) + 9 sin(t), t ≥ 0
Then acceleration and velocity is
v(t) = s′(t) = −9sin(t)+9cos(t)
a(t) = v′(t) = −9cos(t) −9sin(t)
Answer:
C
