Question

REFER TO PICTURE FOR SET UP

The trajectories of two particles are given by

Particle A: r 1 → ( t ) = ⟨ t 2 , 7 t − 12 , t 2 ⟩

Particle B: r 2 → ( t ) = ⟨ 4 t − 3 , t 2 , 5 t − 6 ⟩

Do the particles ever collide? If so, at what time?
When the particles collide, are they moving in similar directions or opposite directions? Find the angle between their tangent vectors. (Give your answer in degrees, between 0 and 180.)
When the particles collide, which particle is moving faster? Justify your answer.

3. The trajectories of two particles are given by
Particle A: i (t) = (t², 7t – 12, t²)
