The end of one of the prongs of a tuning fork that executes simple harmonic motion of frequency 875 hz has an amplitude of 0.30 mm.
(a) find the maximum acceleration of the end of the prong.
(b) find the maximum speed of the end of the prong.
(c) find the acceleration of the end of the prong when the end has a displacement of 0.1 mm.
(d) find the speed of the end of the prong at this time.

(a)9.07×10^3 rad/s^2

(b) 1.65 m/s

(c) 3.02 ×10^3 rad/s^2

(d) 0.55m/s

Explanation:

Amplitude A = 0.30mm

f = 875Hz

Angular frequency w = 2πf

= 2×3.142×875= 5498.5 rad/s

Maximum acceleration = w^2A

= 5498.5^2× 0.3×10^-3

= 9.07×10^3rad/s^2

Maximum velocity v =wA

=1.65m/s

Acceleration at the end of the prong where displacement is 0.1mm

a =w^2x

a= = 5498.5^2× 0.1×10^-3

=3.02×10^3 rad/s^2

v =wx

v = 5498.5 × 0.1×10^-3

=0.55m/s

33: answer is c

i really hope this answer you out! it makes my day people like you and giving back to the community that has me through school! if you could do me a favor, if this you and this is the very best answer and you understand that all of my answers are legit and top notch. mark as brainliest! and have a awesome day!

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
