Some work will be done on friction between wheels and road but it is negligible compared to work done on friction on breaks.
W = Ek = (m*v^2)/2 = 2000*22^2/2 = 1000*22^2 = 484KJ
Because car is not changing its potential energy, there is no work to be done on while changing it which means that all goes on changing kinetic energy (energy of motion)
Answer:
is a reflection.
The image is real light rays actually focus at the image location). As the object moves towards the mirror the image location moves further away from the mirror and the image size grows (but the image is still inverted). When the object is that the focal point, the image is at infinity.
Explanation:
Answer:
The transverse displacement is 
Explanation:
From the question we are told that
The generally equation for the mechanical wave is
The speed of the transverse wave is 
The amplitude of the transverse wave is 
The wavelength of the transverse wave is 
At t= 0.150s , x = 1.51 m
The angular frequency of the wave is mathematically represented as
Substituting values
The propagation constant k is mathematically represented as
Substituting values
Substituting values into the equation for mechanical waves
The total force that the SUV exerts is:
F = 2000 kg * 3 m/s^2
F = 6000 N
Since a resisting force amounting to 1500 N is exerted,
then the force exerted by the SUV tires is:
F tire = 6000 N – 1500 N
F tire = 4500 N
The correct option is B.
Sunglasses are designed to block polarized light. If you are driving toward the sun, most of the sun's glare will be coming to you horizontally, thus, the best sunglasses to wear is the one, that will block the horizontal glare and allow only the vertical glare to pass through.
