WebSep 25, 2024 · e 1 = 20 sing ωt − here phase angle with X-axis is zero, hence the vector will be drawn parallel to the X-axis . e 2 = 30 sin (ωt − π/4) − its vector will be below OX by 45° e 3 = 40 cos (ωt + π/6) = 40 sin (90° + ωt + π/6)* = 40 sin (ωt + 120°) − its vector will be at 120° with respect to OX in counter clockwise direction. Webt = [2π − π/5] / ω = 4.2518 s. (iv) At minimum amplitude, x = −4, so we have −4 = 4cos(ωt + π/5) . Dividing through by 4, we get −1 = cos(ωt + π/5) . Taking the inverse of both sides, the solution is ωt + π/5 = cos−1(−1) , and thus, t = [cos−1(−1) − π/5] / ω .
