True i think like ya cut g
Answer:
the angle, in radians, between the central maximum = 2.87degree or 0.05radians
Explanation:
The detailed steps and appropriate formula is as shown in the attachment.
Using λm = dsin teta
where d =20λ, m = 1
from the formula, sin teta = λ/20λ
= sin teta = 0.05
teta = arc sin(0.05) = 2.87 degree
F = ma (force = mass x acceleration)
So the car’s mass affects the amount of force, changing how it would roll down a ramp, I think.

Answer:
t = 376.99 s
Explanation:
We must solve this problem with the equations and kinematics, let's start by looking for the speed of the vehicle,
v = d / t
v = 7/40
v = 0.175 m / s
Since the speed e remains constant, we must find the length of the circle is
L = 2π r
L = 2π 21
L = 131.95 m
In the problem it does not specify clearly, but in general the curves of the road correspond to half a circle, so the length of the road is
L ’= L / 2
L ’= 131.95 / 2 = 65.97 m
as the speed is constant
t = L ’/ v
t = 65.97 / 0.175
t = 376.99 s
