The question is missing, but I guess the problem is asking for the location of the image.

We can solve the problem by using the mirror equation:
\frac{1}{f}= \frac{1}{d_o}+ \frac{1}{d_i}
where
f is the focal length of the mirror
d_o is the distance of the object from the mirror
d_i is the distance of the image from the mirror

For a convex mirror, the focal length is taken as negative, so in our problem 
f=-2.2 m
The distance the object is
d_o=4.4 m

And if we use the previous equation, we can find the distance of the image from the mirror:
\frac{1}{d_i}= \frac{1}{f}- \frac{1}{d_o}= -\frac{1}{2.2 m} - \frac{1}{4.4 m}    =- \frac{3}{4.4 m}
from which we find
d_i =  -\frac{4.4 m}{3}=-1,47 m
where the negative sign means the image is virtual (located behind the mirror)

vaieri [72.5K]
Double the amount of people because the ramp went from 10-meter to 20-meter, so times by 2. 4 times 2 is 8.
The answer is 8 people.
Hope this helps!

Two forces act on a 41-kg object. One force has magnitude 65 N directed 59° clockwise from the positive x-axis, and the other ha
Genrish500 [490]

Answer:

a = 1.41 m/s²

Explanation:

Given that

mass ,m= 41 kg

F₁ = 65 N , θ = 59°

F₂ = 35 N ,θ = 32°

The component of Force F₁

F₁x= F₁cos59° i

F₁x= 65 x cos59° i = 33.47 i

F₁y= - F₁ sin 59° j

F₁y= - 65 x sin 59° j = - 55.71 j

The component of Force F₂

F₂x= F₂ sin 32° i

F₂x= 35 x sin 32° i = 18.54 i

F₂y=  F₂ cos 32° j

F₂y=  35 x cos 32° j =  29.68 j

The total force F

F= 33.47 i +   18.54 i - 55.71 j +   29.68 j

F= 52.01 i - 26.03 j

The magnitude of the force F

F=\sqrt{52.01^2+26.03 ^2}\ N

F=58.16 N

We know that

F= m a

a= Acceleration

m=mass

58.16 = 41 x a

a = 1.41 m/s²
