Sagot :
Answer:
Explanation:
y = Acos(ωt + φ)
ω = 2π
φ = -2π/3
A = 4
v = -ωAsin(ωt + φ)
a = -ω²Acos(ωt + φ)
y(0) = 4cos(-2π/3) = -2 m
v(0) = -2π(4)sin(-2π/3) = -21.77 m/s
a(0) = -(2π)²(4)cos(-2π/3) = 78.96 m/s²
y(2,75) = 4cos(2π(2,75) - 2π/3) = -3.46 m
v(2,75) = -2π(4)sin(2π(2,75) - 2π/3) = -12.57 m/s
a(2,75) = -(2π)²(4)cos(2π(2,75) - 2π/3) = 136.76m/s²
