While driving down the road, a firefly strikes the windshield of a bus and makes a quite obvious mess in front of the face of th

e driver. This is a clear case of Newton's third law of motion. The firefly hit the bus and the bus hits the firefly. Which of the two forces is greater: the force on the firefly or the force on the bus?

Answer:

Both forces have the same magnitude

Explanation:

1) Notation

F_{bus}= force exterted by the bus to the firefly

F_{firefly}= force exterded by the firefly to the bus

2) Analysis for the situation

The reason why is from the Third law of Newton that states: "For every action, there is an equal reaction force on the opposite direction to the original action force".

For this special case on math terms we have:

F_{bus}=F_{firefly}

The fact that the firefly splatter on this case is because since have a smaller mass, it is less able to stand up to the larger acceleration from the interaction.

3) Conclusion

Based on this analysis, each force would have the same magnitude, so none force is greater than the other.

A uniform steel plate has an area of 0.819 m2. When subjected to a temperature difference between its sides, a heat current* of
Tju [1.3M]

Answer:

ΔT / Δx = 771 K/m

ΔT = 771 x 0.0475 = 36.62 k

Explanation:

P = 31700 W, A = 0.819 m^2, Δx = 0.0475 m, K = 50.2 W /m k

Use the formula of conduction of heat

H / t = K A x ΔT / Δx

So, ΔT / Δx = P / K A

ΔT / Δx = 31700 / (50.2 x 0.819)

ΔT / Δx = 771 K/m

Now

ΔT = 771 x 0.0475 = 36.62 k

A car of mass 960 kg is free-wheeling down an incline at a constant speed of 9.0 m s–1.
Orlov [11]
Need to draw it first.....
but there is no option here to draw ..  why?
anyway ,  here the car is going with a uniform velocity..
so the acceleration of the car=0, a=0
so   resistive force on the car=component along the inclined plane of the weight of the car=mg*cos(90-15)=960*9.8*cos 75=?

A speed truck locks it’s brakes and it skids to a stop. If the truck’s total mass were doubled, it’s skidding distance would be?
Gnom [1K]

Answer:

The skidding distance would be doubled

Explanation:

When the truck applies the brakes and slows down, its motion is a uniformly accelerated motion, so its skidding distance can be found by using the suvat equation

v^2-u^2=2as

where

v = 0 is the final velocity (zero since the truck comes to a stop)

u is the initial velocity

a is the acceleration

s is the skidding distance

The acceleration can also be written as

a=\frac{F}{m}

where F is the force applied by the brakes and m the mass of the truck. Substituting into the previous equation,

-u^2 = 2\frac{F}{m}s\\s = -\frac{mu^2}{2F}

We see that the skidding distance is proportional to the mass: therefore, if the mass of the truck is doubled, the skidding distance will double as well.
