Physics
1 answer:

5 0

Answer:

C -) The friction between an object and air.

Explanation:

The frictional force is the force that exists between two surfaces in contact, which is opposed to the movement.

That is, this type of force exists as long as there is physical contact between surfaces.

While the other types of force always act at a separation distance between bodies.

A railroad track and a road cross at right angle. An observer stands on the road 70 meters south of the crossing and watches an
fgiga [73]

Answer:

The train is moving with a speed of 57.6 m/s.    

Explanation:

Given that,

Distance of observer from the road, d = 40 m (due south)

Velocity of the train, v = 60 m/s (due east)

So,

x(t)=70\\\\y(t)=60t

t is time

Net displacement is given by :

z(t)=\sqrt{(60t)^2+(70)^2}

Differentiating above equation wrt t as :

z'(t)=\dfrac{1}{2}(3600t^2+4900)^{-1/2}{\cdot} 7200t

Put t = 4 s

z'(4)=\dfrac{1}{2}(3600(4)^2+4900)^{-1/2}{\cdot} 7200(4)\\\\z'(4)=57.6\ m

So, the train is moving with a speed of 57.6 m/s.
