Exercise
A particle moves according to the law of motion
r(t)=cos(α)cos(ωt)i+sin(α)cos(ωt)j+sin(ωt)k
Where
ω>0
Calculate their velocity, acceleration and their values (vector sizes).
Final Answer
v(t)=ωcos(α)sin(ωt)i−ωsin(α)sin(ωt)j+ωcos(ωt)k
∣v(t)∣=ω
a(t)=−ω2cos(α)cos(ωt)i−ω2sin(α)cos(ωt)j−ω2sin(ωt)k
∣a(t)∣=ω2
