A car is stopped at a traffic light. When the light turns green, the car starts from rest with an acceleration of 2.5 m/s2 . Als
erma4kov [3.2K]

Answer:

a) f = 453.3Hz

b) f = 443.1Hz

c) f = 420Hz

Explanation:

First of all we need to know the positions and velocities of both vehicles.

For the car:

Xc(-5) = 0m;   Vc(-5) = 0m/s

Xc(5) = 2.5*5^2/2=31.25m;  Vc(5)=2.5*5 = 12.5m/s

Xc(10)=2.5*10^2/2=125m;    Vc(10)=2.5*10=25m/s

For the truck:

Xt(-5)=10*(-5) = -50m;   Vt(5)=10m/s

Xt(5)=10*5 = 50m;       Vt(5)=10m/s

Xt(10)=10*10=100m;     Vt(10)=10m/s

Now for part a) t=-5s. The truck is behind the car, so:

f=\frac{C}{C-Vt}*fo = 453.3Hz

Now for part b) t=5s. The car is behind the truck, so:

f=\frac{C+Vc}{C+Vt}*fo = 443.1Hz

Now for part b) t=10s. The truck is behind the car, so:

f=\frac{C-Vc}{C-Vt}*fo = 420Hz

When an object is located 32 cm to the left of the lens, the image is formed 17 cm to the right of the lens. What is the focal l
Harman [31]

Answer: 11.1cm

Explanation:

Object distance (u) = 32cm

Image distance(v) = 17cm

Focal length(f) =?

Lens formular:

1/f = 1/u + 1/v

1/f = 1/32 + 1/17

Taking the L. C. M of 17 and 32

1/f = (17 + 32) / 544

1/f = 49/544

Taking the reciprocal

f = 544/49

f = 11.1 cm

Therefore, Focal length of the lens is 11.1cm
