A mass attached to a horizontal spring is pulled to the right at t=0. The mass passes x=+10 cm at t=0.3s with a velocity 85.7cm/s. What is a) frequency b)amplitude c) phase constant
The Attempt at a Solution
knowing that Acos(ω0.3+phi)= 10
diving v(t) by x(t) gets
and for phi since at t=0 x I assume is A but I am not sure so 1=cos(0+phi) so phi would be zero
and amplitude is hard to find but it is the original stretched amount I think.
