I done the first part of the question and found k to be 0.025 N/m
Maximum velocity occurs when
v = ωA, and at t=0 x=A?
So hence maximum velocity would be 2 m/s
Using ω^2= k/m
Assuming the above is correct, maximum velocity would first be reached when the
sin(ωt) term is first equal to zero?
Any help would be great 🙂 thanks
