Answer:
<em>The fly should need to move at 9,534.6 m/s to have the same kinetic energy as the automobile</em>
Explanation:
<u>Kinetic Energy
</u>
Is the capacity of a body to do work due to its speed and is computed by
We are not given enough data to compare the kinetic energy of the fly with that of the automobile. We'll assume the following characteristics:
So its kinetic energy is
The mass of the fly is
To have the same kinetic as the automobile:
Solving for 
The fly should need to move at 9,534.6 m/s to have the same kinetic energy as the automobile
Answer:
Explanation:
F=kx
x=F/k
F=2000 kg
x=100 cm=9*10^-3
effective spring constant=k=F/x
k=2000/9*10^-3=2.2*10^-5
now frequency
f=1/2π√k/m
f=1/2*3.14√2.2*10^-5/310
f=1/6.28√7.097*10^-8
f=1/6.28*2.7*10^-4
f=0.16*2.7*10^-4
f=4.32*10^-5
Answer:
Magnitude of the third vector: 57.85 cm
The direction of the third vector: 44.76 N of W
Explanation:
Answer:
See explanations below
Explanation:
Power = Workdone/Time
Power of washer = 450watts
Time used to clean the clothes = 1hour = 3600secs
Energy used to clean a load of clothes in 1 hour of
washing = 450/3600
Energy used to clean a load of clothes in 1 hour of
washing = 0.125Joules
For drying;
Energy = 3000/1.5*3600
Energy = 3000/5400
Energy = 0.556Joules
Hence the energy in washing id 0.556Joules
