I’m so so sorry I wish I could help.... My best answer is no because they have different shapes but I am not sure
Answer:
The motorbike is traveling at 40 m/s
Explanation:
100m over 2.5 seconds or 100/2.5 is 40 m/s
Yes it is work because when you throw a ball, you transfer energy to it and it moves.
a) 189.2 J
b) 13.5 W
Explanation:
a)
The work done by the force on the package is equal to the scalar product between force and displacement:
where F is the force and d is the displacement.
In this problem, the force is:
We know the initial position:
and the final position:
So, the displacement is the difference between the two positions:
Therefore, the scalar product between force and displacement is:
b)
The average power of the machine is the rate of work done per unit time; it is given by
where
W is the work done
t is the time elapsed
In this problem, we have:
W = 189.2 J (work done)
t = 14.0 - 0 = 14.0 s (time elapsed)
Therefore, the average power of the machine is:
Answer:
E = 0.13 J
Explanation:
At resonance condition we have
now if the frequency is double that of resonance condition then we have
now we have
now average power is given as
Now time period is given as
so total energy consumed is given as
