If the frequency of a system undergoing simple harmonic motion doubles, by what factor does the maximum value of acceleration change? a. 4
b. 2/pi
c. 2
d. (2)^1/2

the answers the correct one is a  4

Explanation:

The centripetal acceleration is by

           a = v² / R

angular and linear velocities are related

           v = w R

let's substitute

           a = w² R

for initial condition

           a₀ = w₀² R

suppose the initial angular velocity is wo, suppose the angular velocity doubles

           a = (2w₀)² R

           a = 4 (w₀² R)

           a = 4 a₀

when reviewing the answers the correct one is a

the answer is definitely c.
