krypton

A mass is oscillating on a spring with a period of 1.20 s. At t = 0 the mass has zero speed and is at x = 4.85 cm. What is the magnitude of the acceleration at t = 3.30 s?

    V=0 =>X=Xmax=maggnute=A=4.85^-2 m T=1.2 sec ω=2π/Τ α=-ω^2 * Α sin(ω t + π/2) go for it

    α=-ω^2 * Α sin(ω t + π/2) this is my amplitude A=4.85^-2 m ? and this is my \[w=2\pi f\] and my acceleration is this α?

    i suppose if given x to cm acceleretion will be acceptable to -478.1906 cm/sec^2 (yes minus)

    you did nt put the whole value? -478.20 should be our ans according to given values i wrote the accurate number as i am used to (sorry)
