Answer: v = (33320 - 340f2)/( f2 + 98)

Explanation: this question refers to Doppler effect, hence,

f1 = { V / (V - v)} x f2

f1 = 98Hz, f2 = 76 Hz, V = 340m/s, v = ?, fs = fsourcs

For f1,

98 = { 340 / (340 + v)} x fs ...(i)

for f2,

f2 = { 340 / (340 - v)} x fs ... (ii)

Divide (ii) by (i)

98/f2 = [{ 340 / (340 + v)} x fs]÷ [ 340 / (340 - v)} x fs]

98/f2 = {340 / (340 + v)} x fs x (340 - v)} / 340 x fs

98/f2 = (340 + v)/ (340 - v)

Cross multiplying

98(340 - v) = f2 (340 + v)

33320 - 98v = 340f2 + vf2

Collecting like terms

vf2 +98v = 33320 - 340f2

v(f2 +98) = 33320 - 340f2

v = (33320 - 340f2)/( f2 + 98)

How much power is used by car when it applies 40,000 J of work over a 5.6 second interval
Tcecarenko [31]

Answer:

7142.86W

Explanation:

Given parameters:

Work done by brake  = 40000J

Time taken = 5.6s

Unknown:

Power used by car  = ?

Solution:

Power can be defined as the rate at which work is done. It is mathematically expressed as;

        Power = \frac{work done }{time taken}

Now input the variables;

           Power  = \frac{40000}{5.6}   = 7142.86W
