An orchestra is practicing a piece that is to be played at an allegro tempo. The conductor sets a metronome at 160 beats per min

omeli [17]

Answer:

375 ms

Explanation:

the frequency of metronome , f = 160 beats per minute

f = 160 /60 beats per sec

f = 2.67 beats /s

the period of a single beat , T = 1/f

T = 1/2.67 s

T = 0.375 s = 375 ms

the period of a single beat is 375 ms

Answer:

$a_c=1.57\frac{m}{s^2}$

Explanation:

In order to find its centripetal acceleration we need to use the next equation:

$a_c=\frac{v^2}{r}$

So, we need to find its velocity in first place. Considering that the time T required for one complete revolution is called the period. For constant speed is given by:

$T=\frac{2\pi r}{v}$

Solving for v, considering that in this case T=1.3min=78s, and r=242

$v=\frac{2\pi *(242)}{78} =19.49398518m/s$

Finally, replacing v in the centripetal acceleration equation:

$a_c=\frac{(19.49398518)^{2} }{242}=1.570311811m/s^2$
