1)What is the spring constant of the spring? I got this correct as 302.83 using (mg)/(x)

2)What is the oscillation frequency? I got this correct as 1.039 using w^2= k/m

3) After t = 0.37 s what is the speed of the block? I got this correct using v=-wacos(wt) answer was 4.496

4) What is the magnitude of the maximum acceleration of the block? I got this one wrong attempt posted below.

so I took the derivative of function in question 3 and got a= w^(2)asin(wt) now I then plugged in wa from question 3, but I was not sure what to plug in for the other w so I plugged in the w I got from problem two into the sin argument and the other w in w^(2)a. I then got .197011 m/s^(2) as my answer which is wrong. what do I need to do to correct this error? thank you for the assistance
