Suppose a car approaches a hill and has an initial speed of
kvv77 [185]

Answer:

a) 1.73*10^5 J

b) 3645 N

Explanation:

106 km/h = 106 * 1000/3600 = 29.4 m/s

If KE = PE, then

mgh = 1/2mv²

gh = 1/2v²

h = v²/2g

h = 29.4² / 2 * 9.81

h = 864.36 / 19.62

h = 44.06 m

Loss of energy = mgΔh

E = 780 * 9.81 * (44.06 - 21.5)

E = 7651.8 * 22.56

E = 172624.6 J

Thus, the amount if energy lost is 1.73*10^5 J

Work done = Force * distance

Force = work done / distance

Force = 172624.6 / (21.5/sin27°)

Force = 172624.6 / 47.36

Force = 3645 N

the gasoline in a car does 40000 j of work on a car and generates a constant force of 20 n. how far did the car go?
NikAS [45]

     Work  =  (force) x (distance)

     40,000 J  =  (20 N) x (distance)

     Distance  =  (40,000 J) / (20 N)

                    =    2,000 meters

                    =     2 kilometers.

(20 N is not a huge force when it's being used to move a car.
It's only about  4.5 pounds.)

Pressure = weight density × depth
Irina-Kira [14]

As we know that pressure due to water is given as

Pressure = (weight density) (Depth)

here we know that

weight density of water = 9800 N/m^3

height of the water = 1.2 m

now from above formula we have

P = 9800 \times 1.2

P = 11760 Pa

so pressure due to water is given as 11760 Pascal

A string with a length of 6.2 m is vibrated at its natural frequency (first harmonic). What is the wavelength of the produced st
svlad2 [7]

Answer:

12.4m

Explanation:

Given

Length of string = 6.2m

L = λ/2 (for natural frequency (first harmonic)

λ = 2L

λ  = 2(6.2)

λ = 12.4m

Hence the wavelength of the produced standing wave is 12.4m
